Heredity is properly defined as being the “sum of the characteristics and potentialities genetically derived from one’s ancestors” (Merriam-Webster Dictionary, 2011). At the time of conception, every embryo is given it share of genetics from each parent’s or donor’s gene pool, which allows the process to create another human being; which we call baby. Genetics tells us what kind of traits that the embryo will inherit through the parent’s or donor’s genes. Either way, there is a possibility that the embryo could either get good genes, or bad genes, or both from either of the parent’s or donor’s genes. Therefore, when both genes are combine, which then become one person traits. When the fetus, is born then it would be exposed to all elements of life till the person dies. In return, because of this exposure to life, this process in return could affect one’s person behavior, regardless of their genes. Genetics by itself does not control one person behavior, but when you add hormone in to the consideration than it’s comes to another factor to consider. When considering a person hormones as a factor, this type of issue cam contribute to the person behavior issues. However, the person hormones according to researchers are now considered to be a powerful drug that the body produces from within the endocrine glands. However, when you put both a person gene and hormones together, this can influence the person behavior.
By research, behavioral development has been known to start at conception, after several studies has been conducted. When both parents’ genes are pass-along to the child, these genes can contribute to the child intelligence, their talents, behavior and any other kind of disorders. However, behavior development can also be ...

... One would not exist without the adrenal hormones that the body produces. However, according to researchers healthy adrenal glands could lead to a healthier body.
Both, the heredity genes and hormones that the body produces can affect and influence the person behavior. Therefore traits that are considered to be purely genetic can be high heritability; while other traits can be influenced by surroundings, environment, and behavior with low heritability. Many traits exist by a mixture of genetics and environment issues. Traits that are inherited could be considered the foundation from which each person can build and shape one’s own distinctive personality. Hormones can be affected by diet, exercise, and medications. Controlling and adapting to the surroundings and environment allow for each person to survive as well as be in control of his or her own destiny.
Through time, psychologists have argued over whether only our genes control our behaviors in life or if the environment and the people surrounding us have any effect in our lives. This is called nature versus nurture. We do not know what dictates our behavior, or if it is a combination of both. One question is, if genes control our behavior, are we really responsible for our actions? I think that if we can make choices we are responsible for our actions. While or genes influence various aspects of our personalities, there is no denying that our environment has some effects too. Our genes make us, but our experiences and our surroundings shape the way we behave as people. The people we grow up with, especially our parents teach us ways of acting and thinking that we keep for the rest of our lives.
This understanding that a child 's behavior is a part of their social development is crucial
Genetics has a great impact on the person one becomes starting with their early development. The Genetic Model will access the gene mutations that affect the individuals. Gene mutations such as, the altering of proteins which in return changes the functions of the brain (McNeece & DiNitto, 2012). Likewise, the individual may be more prone to develop a addiction due to this mutation. Also, genetics can affect the behaviors of an individual participating in the use of drugs. Once a parent participates in drugs and their desires it reflects onto the child’s behaviors and their desire with the use of drugs. These desires are stored in the limbic part of
Behavior is defined as the way in which one acts or conducts oneself, especially toward others. Behavior is controlled by a system of the body called the endocrine system. The endocrine system is made of glands whose secretions pass directly into the bloodstream or lymph system. This system is responsible for growth, mood, tissue function, metabolism, sexual function and reproductive processes. The endocrine system affects almost every organ and cell in the body. Hormones and glands make up this system. As with any system, diseases can occur that are dangerous to the body.
A complex and relatively new field of study, behavioral genetics is particularly interesting because is sheds light on the inner workings of a favorite subject: ourselves. Human behavioral genetics is broadly defined as the examination and characterization of genes as a basis for human behavior. The link between genetics and behavior was first recognized by Sir Francis Galton, a 19th century scientist and cousin of the very famous Charles Darwin, who studied the heritability of mental abilities of close relatives and family members (Stigler, 2010). Since then, genetics has been linked to many more behavioral phenotypes from eating and mating activities to substance abuse, social attitudes, violence and mental abilities. Geneticists are able to study this by analyzing parallels in physical and behavioral characteristics of families and populations (Rothstein, 2005). However, as with many other new scientific fields, the study of behavioral genetics and its implications has been the subject of increasing scrutiny and co...
The impact of genes and environment on human development has been a controversial debate for a long time. On one hand, some people claim that nature is the sole determiner of human development; on the other hand, others assert that nurture is the only determiner of human development. In this paper, possible roles of both biology and environment on cognitive abilities will be discussed through providing a balanced interpretation based on the text and relevant readings from the class.
Epigenetics is the study of how inherited traits are expressed and influenced by the environment, and it is extremely complex. Joseph Nadeau has traced over one hundred biochemical, physiological, and behavioral traits affected by epigenetics. He has seen them be passed down through several generations (Blum, et al, 2010). ADHD, which has been linked to anti-social behavior, is thought to have epigenetic roots. In one adoption-based study done by a group of colleagues, they found that if the mother was an alcoholic or a criminal, the child was at great risk for ADHD. If the father was criminal, the child was also at an increased risk, but having an alcoholic father did not seem to have any effects of the offspring in terms of developing ADHD (Beaver, Nedelec, et al, 2011). Criminal behavior would be the genetic control, and alcoholism would be the environmental factor. Even though they both play a role, genes are still the platform the environment works on to create what ...
“The term “nature versus nurture” is used to refer to a long-running scientific debate. The source of debate is the question of which has a greater influence on development: someone's innate characteristics provided by genetics, or someone's environment. In fact, the nature versus nurture debate has been largely termed obsolete by many researchers, because both innate characteristics and environment play a huge role in development, and they often intersect”. (Smith, 2010 p. 1)
Human behavior is a highly debated topic in the scientific community. While geneticists argue that an individual's innate qualities and genetic makeup cause individual differences in human behavior, psychologists believe that an individual's personal experiences or their environment causes those differences. This debate is known as “nature versus nurture,” and the two sides have evolved as more information has been found in genetic research. While there are still different ideas about how much effect genes and environment have on human behavior, there is a consensus that the two factors work together to influence or predict how a person is most likely to act. But these predictions are not absolute or deterministic, and the factors are not necessarily deterministic.
Kids developing are originally shaped by their environment, which includes how their parents raised them to act along
Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence? Clearly exploration of the nature versus nurture argument with regard to genetic predisposition has social, political, and legal significance.
Someone can physically look like their parents, siblings or even ancestors from the third generation. When a baby is born, it is common to learn in a natural way. No one teaches a baby how to crawl or how to react when he and she is hungry. However, talents, qualities and personalities are developed through experiences. The environment in which people grew up can have a lasting effect or influence on the way they talk, behave and respond to things around. According to Steven Pinker, Behavioral genetics has shown that temperament emerges early in life and remains fairly constant throughout the life span, that much of the variation among people within a culture comes from differences in genes, and that in some cases particular genes can be tied to aspects of cognition, language, and personality (2). Researchers believe that the origin of behaviors occur in genes in the DNA or even animal instincts which this concept is known as nature of human behavior. Other researchers believe that people are they were they are because they are taught to do so. This concept is well known as nurture in human behavior. In society, there will always be the doubt between Do we born in this way or do we behave according to life experiences? I strongly believe that nurture plays an important role in the upbringing of a child and the decisions that one makes in the future. Firstly, humans learn from their environment and other’s behaviors. Secondly, culture is a huge remark in people’s life. Finally,
Undoubtedly, humans are unique and intricate creatures and their development is a complex process. It is this process that leads people to question, is a child’s development influenced by genetics or their environment? This long debate has been at the forefront of psychology for countless decades now and is better known as “Nature versus Nurture”. The continuous controversy over whether or not children develop their psychological attributes based on genetics (nature) or the way in which they have been raised (nurture) has occupied the minds of psychologists for years. Through thorough reading of experiments, studies, and discussions however, it is easy to be convinced that nurture does play a far more important in the development of a human than nature.
The endocrine system is a collection of glands in the body that help to control bodily metabolic activity by producing endocrine secretions. Although there are many glands in the endocrine system the main glands include the pancreas, ovaries, testes, kidneys, thyroid gland, parathyroid gland, adrenal glands, pineal gland, gastrointestinal tract, hypothalamus and pituitary gland.
The distinction between nature versus nurture or even environment versus heredity leads to the question of: does the direct environment or the nature surrounding an adolescent directly influence acts of delinquency, later progressing further into more radical crimes such as murder or psychotic manifestation, or is it directly linked to the hereditary traits and genes passed down from that individual adolescent’s biological parents? To answer this question one must first understand the difference between nature, nurture, environment, and heredity. Nurture, broken down further into environment, is defined as various external or environmental factors one is exposed to which can be more specifically broken down into social and physical aspects. Nature, itself broken down into heredity, is defined as the genetics and the individual characteristics in one’s personality or even human nature.
