Appearance-wise, my parents are poles apart. Everything one is, the other is not. My mother, who was born and raised in the Philippines, has olive-toned skin; dark, thick hair; deep brown, almond-shaped eyes; and has a petite, slender frame. My father, however, is from the United States, and is tall, blue-eyed, light-skinned, and possesses a burly figure. Needless to say, there are visible distinctions between them; these range from the more overt disparities found in their skin color and height, to the more specific variations such as in their nose structure. These variations are manifest in my physical appearance—I exist as the amalgamation of these dissimilarities made tangible. It is the negotiation between dominant and recessive traits …show more content…
As will be shown, hair color, texture, and hairline are all areas of genetic exploration.
An overt partitioning exists in the hair coloring on my mother’s side of the family against that of my father’s side. Among my mother’s relatives, black hair runs rampant. This may be of no surprise given the pervasiveness of dark hair among Filipinos. From the observations I have made from my travels abroad, the typically recessive hair colors, such as blonde and red, are nearly nonexistent in the Philippines (while certainly not impossible, the presence of such colors are anomalous in this country). As far as my father’s family goes, blonde and brown hair colors are the most prevalent, unsurprising given the melting pot that the United States is. Indeed, my mother possesses black hair and my father has blonde (although now grayed) hair. Between the two, my mother possesses the more dominant

Despite my inclination to reach for my flat iron to produce straightness, I have naturally wavy hair. Again my parents present a binary when it comes to hair texture: my mother has thick, curly hair while my father has thin, straight hair. Again, my mother possesses the dominant trait as opposed to my father who has the recessive trait. Unlike hair coloring, however, the mixing of genes among my parents has the result of incomplete dominance, manifested in that I have the intermediate phenotype of wavy hair. A similar Punnett square, in which my mother possesses the CC genotype and my father has a ss genotype, would result in a 100 percent chance of me having wavy hair. Both of my half-siblings mirror my father in that they have straight hair. It is worth noting that in contrast to the previous points, I do exhibit an instance of a recessive trait in my hairline. Whereas my mother has the dominant widow’s peak, my father has the recessive trait of a straight hairline. Despite my lack of a widow’s peak, it is possible that I could still carry that gene which could potentially be passed down to future
In our genes, multiple different alleles determine whether one person will have a certain trait or not. Alleles are what make-up our genotypes and in this lab, we wanted to determine the genotypes of our class in the two loci: TAS2R38 and PV92. The TAS2R38 locus codes for a protein that involves the bitter taste of PTC; the gene determines whether or not a person will taste the PTC paper as very bitter or no taste at all. People with the “T” allele are tasters while those that are homozygous recessive (tt) are non-tasters. The taster locus can be found chromosome 7.3 The two different alleles present in the could be due to the effect of evolution and natural selection because the same can be found in chimps.4 The PV92 locus does not code for any protein but rather involves an Alu element that is 300-bp long. A person with the “+” allele would have the Alu element making that sequence longer while those with the “-“ allele don’t have the element and would have a shorter sequence. This locus can be found on chromosome 16.3 There are multiple Alu sequences found among primate genomes but there are human specific sequences such as the one found on the PV92 locus.1 In the experiment, student DNA was collected from cheek cells and PCR was used to target the loci and amplify the region of DNA. In the taster gene, after amplification, a restriction digest was performed to differentiate between the two alleles. The digest was able to show differentiation because those with the “T” allele would have two bands from gel electrophoresis and those with “t” will have one band because the restriction enzyme doesn’t cut it. For the PV92, we were able to distinguish between the alleles due to the added length of the Alu element. Those...
Media plays a significant role in determining the perception students have on attending school. For instance, if the media portrays the environment in a junior high to be harsh and ruthless, the students will assume a similar situation will occur. The media can change our perception on various levels of issues therefore, we must stay vigilant on the types of programs we allow our youths to watch. From the types of clothing TV actors/actresses wear could be a factor on the type of clothes a student wears to school as well as the stereotypes placed on race and ethnicity based on what the media portrays.
The literature does provide evidence for my hypothesis and also provides a clearer picture as to how frequent and to what extent the interbreeding is believed to occur. Examining these articles will introduce the new findin...
An individual can be homozygous dominant (two dominant alleles, AA), homozygous recessive (two recessive alleles, aa), or heterozygous (one dominant and one recessive allele, Aa). There were two particular crosses that took place in this experiment. The first cross-performed was Ebony Bodies versus Vestigle Wings, where Long wings are dominant over short wings and normal bodies are dominant over black bodies. The other cross that was performed was White versus Wild where red eyes in fruit flies are dominant over white eyes. The purpose of the first experiment, Ebony vs. Vestigle was to see how many of the offspring had normal bodies and normal wings, normal bodies and vestigle wings, ebony bodies and normal wings, and ebony body and vestigle wings.
Convincingly enough, my interview with Ben showed me that in this case, my hypothesis was proven. Although our parents reside from much different backgrounds, we both have values instilled within us that we continuously live our lives by. Ben’s parents have influenced his life in a very religious way while my mother imposed her German ideals that strongly revolved around education and law. With this, I’ve come to find that it does not matter how similar or dissimilar two cultures may be, when it all boils down, we do not only inherit traits from our parents physically, but culturally as well.
In today’s society there are many stereotypes surrounding the black community, specifically young black males. Stereotypes are not always blatantly expressed; it tends to happen subconsciously. Being born as a black male puts a target on your back before you can even make an impact on the world. Majority of these negative stereotypes come from the media, which does not always portray black males in the best light. Around the country black males are stereotyped to be violent, mischievous, disrespectful, lazy and more. Black males are seen as a threat to people of different ethnicities whether it is in the business world, interactions with law enforcement or even being in the general public. The misperceptions of black males the make it extremely difficult for us to thrive and live in modern society. Ultimately, giving us an unfair advantage simply due to the color of our skin; something of which we have no control.
Albinism is a genetically linked disease and is presented at birth; it is characterized as a lack of pigment called melanin that normally gives color to a person’s skin, hair and eyes. This results in milky white hair and skin, and blue- gray eyes. Melanin is synthesized from amino acid called tyrosine, which originates from the enzyme tyrosinase. Albinism affects all races and both sexes; people with this disease have inherited a recessive, nonfunctional tyrosinase allele from both parents (Saladin 189). The inheritance of Albinism is coded in the gene of the parent’s alleles. Alleles are two different versions of the same gene or trait and are found on the same place of a chromosome. One allele is coded for the production of melanin that will produce normal skin, hair and eye color and another allele that represent the lack of melanin that produces abnormal skin, hair and eyes.
Albinism is a genetic condition present at birth, characterized by a small amount of melanin pigment in the skin, hair and eye. Albinism is an occasional inborn sickness related with vision difficult, which affect one in seventeen thousand persons. It is not a contagious disease and cannot be spread over contact. Albinism affects individuals from all races. Most folks with albinism have parents with a normal color of skin. Some may not even recognize that they are Albino until later on in their life. This paper will be based on the study of albinism, causes, types, the genetic transmission and some possible medical problem.
A stereotype is defined as ‘an exaggerated and often prejudiced view of a type of person or group of people’ (Novak, Campbell, & Northcott, 2014, pg. 5). Stereotypes often develop from observations/information that tend to not be true. If they turn out to be true then they are exaggerated and distorted. Further, if someone is found who does not fit the stereotype they are considered to be an exception. Some stereotypes positively portray the elderly but most have a negative impact. This can create prejudice and discrimination towards the elderly which can negatively impact their quality of life (Novac et al., 2014).
middle of paper ... ... avour of "purity of the race" idea, but they understand how it worked. Blond hair and blue eyes are recessive genes. Two brown-eyed people can give birth to a blue-eyed child, but two blue-eyed people cannot give birth to a brown-eyed child. Dark skin and dark hair are also dominant genes, so because of evolution, it must mean that the ancestors of humanity had dominant genes.
My sister was born with blonde hair and she is filled with freckles and she also is very short compared to what we were at her age. She is 5’2 and in eighth grade and when I was in fifth grade I was like 5 6 or 5 7 and I had huge feet and that is just an example with reference to nature vs. nurturing that where hereditary falls in play.
This type of inheritance is called autosomal recessive inheritance. If a parent has a child with albinism, it means the parent must carry the albinism gene. Until recently, unless a person has albinism or has a child with albinism, there was no way of knowing whether he or she carries the gene for albinism. Recently, a test has been developed to identify carriers of the gene for ty-negative albinism and for other types in which the tyrosinase enzyme does not function. The test uses a sample of blood to identify the gene for the tryrosinase enzyme by its DNA code. A similar test can identify type-negative or similar albinism in unborn babies, by aminiocentesis.
Aging is universal and it is a process that everyone has to go through. The only difference is that everyone goes through this process at their own pace influenced by factors that will be discussed later on in this paper. When we think about factors that have an influence on older adults and how their life may be affected, we must consider the different social institutions while analyzing influences from social factors, cultural factors, and personal values. Abuse to older adults, stereotyping and informal care and technological advancements that affect older adults are the three topics that will be discussed in this reflection. Furthermore, will connect the three topics I have chosen to the knowledge that I have gained from my interaction

In the modern era, stereotypes seem to be the ways people justify and simplify the society. Actually, “[s]tereotypes are one way in which we ‘define’ the world in order to see it” (Heilbroner 373). People often prejudge people or objects with grouping them into the categories or styles they know, and then treat the types with their experiences or just follow what other people usually do, without truly understand what and why. Thus, all that caused miscommunication, argument or losing opportunities to broaden the life experience. Stereotypes are usually formed based on an individual’s appearance, race, and gender that would put labels on people.
