Rationale
I chose this topic because there is an issue of homophobia around the world. I find it interesting as to why people are homosexual, and if there is a gene responsible for this or if it can be developed later in life. This area of research directly relates to the age old question of “nature Vs. nurture”.
Introduction
Scientists have asked the question of whether homosexuality is a choice or something the individual has no control over. The search for the ‘gay gene’ is a relatively new study. According to Pease and Bull (2000) the physical sex of an organism is determined by the gonad type, testes or ovaries, as well as secondary sexual traits. An organisms sexual preference is determined by its preferred sexual partner, if the organism prefers to have sex with its own sex, it is classed as homosexual, however if it prefers to have sex with the opposite sex, it is classed as heterosexual. Gender identity is a separate topic that is very pertinent. G-+ender identity is how an organism sees itself, is it male or is it female. The gender identity of an organism can be separated from the sexual preferences, for example, a male who sees himself as female may still have a sexual preference for woman.

... political or other opinion, birth or other status.” However people are still being discriminated against for their choice of sexual partner. In Stephen Fry’s Out there, Fry talks with the parents of a 14 year old Brazilian boy was abducted, tortured and killed because his abductors thought he was homosexual. I feel that even if a ‘gay gene’ is found it will not stop the discrimination, looking at Brazil where gay rights are legalised, there is still a lot of violence and hate crimes.
Conclusion
In conclusion, homosexuality is not caused by a mutation, although it could be an allele that is passed down on the X chromosome. There as many theories as to why there are homosexuals, some say it is nature, others say it is nurture. There are also many limitations which stop us from finding a ‘gay gene’, many of these limitations are due to ethics. [Words: 2888]
The finding mean usually relies in the shadow of the fathers' absence. This could be changed if a father properly trains his son to be candid on his instilled values becoming a man. Therefore, it is not an uplifting question of why homosexuals occurs in the post-modern era. Genes may be related to the development of sexual orientation, recent studies shows that an increased choice of homosexuality in men whose mothers previously carried to many male children.
This represents a change in avenue of attack, not a broad ideological shift from historic eugenic arguments. Similarly, the search for the "gay gene," while a relatively new scientific concept, is highly reminiscent of previous understandings of queer sexuality, which located deviance in physical and/or hormonal "abnormalities." The idea that queer people's queerness is loc...
Most scientists and psychologists believe that homosexuality is caused by a gene determined at birth much like your hair, skin, and eye color are determined, meaning homosexuality is not a choice and is no more a choice than choosing your skin color. Studies known as adoption studies show that sexual preference is genetic by adopting a young infant child and placing them in either a homosexual or h...
Sexuality over the years has been defined and reshaped in many ways by different researchers and experts. In the CNN article, “Being Gay is not a Choice,” James Hormel defines sexuality as something that you are born with and cannot hide or ignore your true identity. In the article, Hormel recalls the times in his life where he felt alone and when he hid the truth. Hormel goes on to state how he “spent the first 35 years of my life trying real hard not to be gay”(Hormel, pg. 1). However, despite Hormel 's views I disagree with this article in many ways as it shows little evidence on how someone could in fact be born gay. An individual decides his identity and sexuality, which in most cases is tied together with how one is raised and the environment in which one is raised in. John Hormel’s article on sexuality can be countered by an article written John D’Emilio. His article, “Capitalism

In Brandon Ambrosino’s “I am Gay – but I Wasn't Born This Way”, the author states his reasoning as to why he believes he chose to be gay. Being one of the few who questions the born this way ideology, Ambrosino, along with other LGBTQ activists, are “cast as homophobic, and their thinking is considered backward”(par 10). However, just because an argument like this is popular, it doesn’t necessarily mean it’s true. Even scientific organizations like the American Psychological Association (APA) believes that people have no control over their sexual orientations, however, no findings have been found that determine if sexual orientation is determined from hormones, genetics, or cultural influences(par 21), therefore contradicting the previous claim.
Sexual orientation is a topic scientists spend a great deal of time researching, however it is unclear what factors really have an effect on one’s sexual orientation. The role of biology, culture, socialization, and age contribute to the influences of sexual orientation.
The first possible cause of homosexuality is genetic factors. Homosexuality is a trait from birth (Buchanan, 2000). Studies found that identical twins share many common traits. A study found that identical twins normally share homosexual behavior if one of them is homosexual. This proved that genes are likely to cause homosexuality. In addition, according to (Santinover, 2002), homosexuality is a heritable behavior. Based on heritability studies, almost any human trait is heritable including the homosexual behavior. He stated that behavioral genes are found in specific chromosome. Thus, the behavior is obviously heritable. Moreover, Italian University of Padova (2004) believes that homosexual trait is passed from mother to male offspring by natural ...
Society is created with both homosexual and heterosexual individuals. Previously when certain laws discriminated against others, such as law for women's rights to vote, these laws were changed. Changing the traditions of the country does not mean that it will lead to the legalization of other extreme issues. Each ...
Though many researchers will agree that homosexuality is not genetic, still, others beg to differ. HRC.org published an article entitled “Guide to Coming Out,” the article states ‘sexuality and gender identity are not choices any more than being left-handed or having brown eyes or being heterosexual are choices…The choice is in deciding how to live your life.’ With society always shoving their view into the minds of Americans second of everyday, it is not that hard to see where the confusion arises.
From the moment people born, there are certain basic functions that will be with them throughout their lives. The abilities to eat, breathe, sleep, or to have the capacity to learn are a natural occurrence for most people. There are, however, traits that are specific to each individual. They are traits that set them apart from everyone else. The traits such as eye color, ones dominate hand, or susceptibility to a specific disease are a few traits that aren’t easily changed. However, there are some that are controversially questioned as to whether or not one is born with the trait or if it is a learned behavior. One of the biggest of these controversies is the question of whether sexual orientation is a choice or something that is beyond the individual’s influence. Although the evidence is commonly disregarded because of personal beliefs or opinions, sexual orientation is not a choice.
If a faculty advisor censors an article written by a gay student, they are following their traditional viewpoints against the homosexual lifestyle. Several researchers have addressed the issue of sexual preferences and consequential discriminative beliefs. According to research by Herek (1987), religion is one of the most important social agents in defining viewpoints against homosexuality, and their intolerance reflects on both the academic community and the entire society. As a moral realist, I cannot form prejudices because the main rule of moral realism states that the objective truth is not related to subjective beliefs. The perlocutionary analysis will be used in evaluating and responding to the issue because my goal is to persuade the faculty advisor that censoring articles based the author's sexual preferences is morally incorrect. In the letter, I will aim to persuade the faculty advisor that the ethical decision-making model behind removing the article is at fault, and I will explain both personal and community worldviews that endorse diversity while avoiding generalized statements to preserve the relationship with my significant other.
Homosexuality in Today's Society. In today's society, there exists a mixture of issues which tend to raise arguments with people all over. There are a handful of topics that always seem to escalate these differences between people to the point where one who earnestly participates in discussion, debate and argument can direct their anger towards their feelings on the person themselves. Some examples of such delicate subjects are the death penalty, abortion, and euthanasia.
In order to discuss the biology of gender identity and sexual orientation, it is necessary to first examine the differences between multiple definitions that are often mistakenly interchanged: sex, gender, sexual orientation, and gender identity. Sexual orientation is defined by LeVay (2011) as “the trait that predisposes us to experience sexual attraction to people of the same sex as ourselves, to persons of the other sex, or to both sexes” (p. 1). The typical categories of sexual orientation are homosexual, heterosexual and bisexual. Vrangalova and Savin-Williams (2012) found that most people identify as heterosexual, but there are also groups of people that identify as mostly heterosexual and mostly gay within the three traditional categories (p. 89). This is to say that there are not three concrete groups, but sexual orientation is a continuum and one can even fluctuate on it over time. LeVay (2011) also defines gender as “the ...
