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]
