The Importance of Mendel’s Laws in Modern Genetics
-
Human genome is like an intricate library that stores vast volumes of life information. The preservation and passage of genetic books to future generation is one of the primary tasks of human genome.
In the late 19th century not too long after the library of Congress was built in the United States, Gregor Mendel, an Austrian teacher and abbot, made a keen observation in the garden of a monastery at Brno. After testing and breeding 28,000 pea plants, Mendel discovered the mathematic pattern of describing how parents pass on their traits to the offspring. This finding laid a foundation for Modern Genetics, although we can image that Mendel did not even know what constituted the genetic building block at the time.
About a century later, the work of Francis Crick and James Watson led to the discovery of DNA as genetic code carrier.1 Our genetic makeup comprises 3 billion base pairs of DNA molecules and the variations of DNA sequences lead to the diversity and individual uniqueness among the life on earth. However, within this vast library of genetic codes, errors will inevitably occur, like a misplaced book, resulting in diseases or increased vulnerability to harmful insults. Unfortunately, some genetic defects can pass on to affect future generations.
Completed in 2003, the Human Genome Project is an extraordinary international scientific collaboration to decipher human genetic code. The decoding of human DNA sequence provides us a sketch of the entire human genome information. Today scientists can determine the complete DNA sequences of 25,000 human genes and access this information with a simple 30 second search. Using this genetic reference, we will advance our kno...

...overed more than a hundred years ago still helps doctors understand how the gene transmits from shelf to shelf or from generation to generation. In addition, it helps scientist to zero in on defected genes. Analogue to the Dewey Decimal System, the Laws of Mendel accurately predicts a hereditary pattern of a genetic disease or trait even in the days of e-library.

Throughout out the course of human development, scientists will continue to find new new ways to help the human race through the discovery of the human gene inside of each of us, its uses, as well as complications, that can help the survival of our species.
In the 19th century Gregor Mendel accomplished pioneered the first laws of genetics after crossing peas. He conducted an experiment with pea plants. He would use a paintbrush to transfer the genetic coding from one pea plant to another, so he could know exactly who the parents were. With the end of this experiment Mendel came up with two laws; Mendel 's law of segregation, and Mendel 's law of independent assortment. Mendel crossed over purple pea flowers with white pea flowers, which gave him purple pea flowers for the first generation also called F1. Since the offspring were all purple flowers Mendel understood that the purple gene was the dominant gene. Mendel decided to cross the F1 generation with themselves. Which resulted in three purple pea flowers and one white pea flower. By using basic Punnett square, and identify the genotype as PP and the phenotype as pp. This gave Mendel the following ratio of 3:1, three purple pea flowers and one
Other groups had the same results that we ended up with which meant we were doing something right. This experiment was focused on fruit flies, however the same rules apply to humans and most living things, so we can learn where our traits were passed down to us and how. One of Mendel's laws is the law of inheritance and it is the law that is focused on in this lab and is important to our everyday life as
Gregor Mendel was born into a German family, as a young man Mendel worked as a gardener and studied beekeeping. In his later life Mendel gained his fame as the founder of the modern science of genetics. The research that was his claim to fame was his pea plant experiment. Mendel looked at seven different characteristics of the pea plants. For example with seed colors when he bred a yellow pea and green pea together their offspring plant was always yellow. Though, in the next generation of plants, the green peas reemerged at a 1:3 ratio. To explain what he had discovered, Mendel put together the terms “recessive” and “dominant” in reference to specific traits. Such as, in the previous example the green peas were recessive and the yellow peas
The book Genome by Matt Ridley tells the story of the relationship between genome and life by examining the twenty three chromosomes of the human DNA. Each chromosome literally and metaphorically becomes a chapter in the literal and metaphorical book of DNA. In this book of DNA, Ridley examines a particular aspect of the chromosomes chapter by chapter to see how it affects life and humanity’s understanding of life, humans and genetics itself. Although each chapter dives into different aspects of DNA and gathers stories as varied as the genes’ applications, Ridley connects them with important ideas about life and humanity’s understanding of life.
These discoveries about the structure of DNA allowed scientists to explore the genome and develop a stronger understanding of genes. Within a decade of its discovery, other scientists had identified the genes responsible for specific diseases and traits. The discovery of the structure of DNA created a basis for ...
Heredity was a concept that little was known about before the 20th century. In that era, there were two main concepts that most followed about heredity. First, that heredity occurred within a species, and second, that traits were given directly from parents to offspring. These ideas led people to believe that inheritance was the result of a blend of traits within a fixed, unchanging species. In 1856, Gregor Mendel began his experiments in which he would discover the basic underlying principles of heredity.
Mendel wrote that genes are passed from parents to their children and can produce the same physical characteristics as the parents.
Today, scientists know the specific locations of 1,400 genes on the human genome that, when defective, cause some form of genetic disease (Lucassen 139). In addition to this, genetic diseases account for thirty percent of all children admitted to hospitals (Lucassen 139). Unfortunately, at this point in time, there are no miracle cu...
In the 19th century, Mendel’s relatively new science of inheritance and hereditary has increasingly developed into what we commonly understand today as genetics. Peter J. Bowler describes this field as becoming “a very active area of scientific research”.
The purpose of the human genome project was to select the best pairs of the genes and the desirable characteristics in the human beings to maintain the production of the organisms according to the desirable gene sequencing. This project was initiated to control the sequencing of the gene artificially [1]. The world’s largest biological plan was the human genome project as it was started on the large scale. The idea of this project was given by the researchers in 1984. The practical work started in 1990 to execute the project. The official declaration of the project carried out in 2003. The financial assistance was awarded to the program setup through the healthcare workplaces, where their engagement was significant. Another program
For numerous years, the world’s most prestigious geneticists have been trying to crack the human genetic code, the intricate puzzle that defines each and every one of us as individuals. With the monumental success of the Human Genome Project, a new and exciting biological frontier is ready for exploration. The ramifications of the knowledge derived from this endeavor will no doubt be staggering for residents of the Rio Grande Valley and the world at large.
Discoveries in DNA, cell biology, evolution, and biotechnology have been among the major achievements in biology over the past 200 years, with accelerated discoveries and insight’s over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be the most important and describe their significance to society, health, and the culture of modern life. DNA (deoxyribonucleic acid) is a self-replicating molecule or material present in nearly all living organisms as the main constituent in chromosomes. It encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.
Genetic testing has become very popular as technology has improved, and has opened many doors in the scientific community. Genetic testing first started in 1866 by a scientist known as, Gregor Mendel, when he published his work on pea plants. The rest was history after his eyes opening experiments on pea plants. However, like any other scientific discovery, it bought conflicts which caused major controversies and a large population disagreed with the concept of playing with the genetic codes of human beings. Playing God was the main argument that people argument that people had against genetics. genetic testing became one of the major conflicts conflicts to talk about, due to the fact that parents could now have the option of deciding if they
Gregor Mendel, born as Johann Mendel, is considered to be one of the most significant historic scientist of all time. He was an Austrian scientist and monk and is best known as the “Father of Modern Genetics.” He founded the science of genetics and discovered many things that dealt with heredity that still applies to our world today. He is remembered for paving the way for scientists and future generations to come. Unfortunately, Mendel’s work went unnoticed until 16 years after his death and 34 years after he published his research. Though Mendel lay covered in his grave, his work would eventually be uncovered. Although Mendel was not there to see it,
