How Does Gay Genes Affect Homosexuality? Essay

Many scientists have a difficult time understanding homosexuality on the evolutionary aspect. They believe a human beings’ main purpose is reproduction, which makes the sexual relationship between two males a confusing concept for most evolutionary thinkers (McKnight 1). Evolutionary thinkers believe that the less desirable genes are removed from the system when they are not breed as often, but this cannot be said for homosexual males who have been a continuing presence in most societies over numerous generations (McKnight 1). These evolutionary thinkers, like most humans, have a need to place others into

The article dives into the 'gay gene’; a gene where individuals had hoped that would be the answer to peoples orientation. While scientists have found some new information regarding chromosomes and genetics, there still is no simple answer that reassures anyone that there is a single 'gay gene ' that defines their orientation.

Another research suggests that sexual orientation is impacted by a gene or genes found on the X chromosome. Though genetic tendencies for homosexuality may be passed from mothers to their children (Rahman & Wilson, 2003). During human evolution, homosexuality was developed to minimize competition between males for a limited number of potential female mates (Schulling, 2004).

If sexuality is developed at an early stage in a person’s life, then how does homosexuality occur? Homosexuality in Darwin’s selection theory doesn’t even exist. (Roughgarden, 2009, 127) Some say that it’s based on the person’s surrounding environment and influences while others say that it’s purely genetic. There has been substantial evidence that points to both genetic and environmental factors in developing homosexuality, but no one factor that clearly pushes over the top to define the origins of homosexuality. Statistically if a male is straight then there is a 4% percent chance that his brother might be gay, but if the male himself is gay, then the percentage jumps to 22%. (Roughgarden 2009: 247) These statistics simply show that gay males tend to group in families, it doesn’t necessarily point out anything specific about the environment’s effects or the male’s genetic makeup. (Roughgarden, 2009, 247)

In one article by Marcia Malory, “Homosexuality & Choice: Are Gay People ‘Born This Way’”, she goes into multiple studies on the genetics of a gay child's parents. A study conducted in 1993 the “gay gene” matter arose when it was looked into the homosexual children's parents having a different X chromosome marker. Nonetheless genes do not control our behavior completely as does environment. The brain may also play a role in sexual preference, like the study in 1991 showing the difference in neurons and pituitary glands. Later in the 2000s more studies showed that gay men have more symmetrical hemisphere and amygdala resembles that of women's. The brain develops in the womb and continues through late adulthood. When did a fetus choose its

Sexual orientation is something that people hear about daily in the news, media, and daily lives of others, especially when it comes to the field of psychology and the nature versus nurture debate. For being as commonly debated and discussed as it is, there are many questions that come along with it: what is sexual orientation, how do people know their sexual orientation, what causes homosexuality, is it normal, is it possible to change, and can wanting LGBT, lesbian, gay, bisexual, and transgender, youth to change lead to suicide?

The nature and nature of homosexuality is heavily debated. Some people believe that homosexuality is biologically determined and others believe it’s base on ones environment. This topic can be argue to be base on both nature and nurture. Studies conducted in the past decades support both the biological and environmental aspect of homosexuality.

The world has come very far with all the dramatic changes we have faced over the years. Wouldn’t you agree? As much change as the world has been through there are still numerous social problems that still exist in society today. Amongst those numerous social problems, sexual orientation and inequality stand out to me. Research from biology, psychology, and sociology is where our understanding of sexual orientation comes from. There are two hypothetical theories researchers have discovered examining the biological basis toward sexual orientation. One concept is the neurohormonal theory, biologist contend that homosexuality is caused by abnormal sex hormone levels in utero. The alternative theory is based on behavioral genetics, determining the source and magnitude of genetic impact on sexual orientation. This theory suggested the concept that gay men were genetically female. Later this theory was proven to be false. Homosexuality was considered as a pathology or mental illness. Not every psychologists agreed with that perspective. A researcher by the name of Havelock Ellis stated that homosexuality was congenital and for that reason it could not be considered as a disease. Sigmund Freud another theorist had the concept that everyone is born bisexual and that either homosexuality or heterosexuality is developed through social and personal experience. Ellis and Freud both concurred that homosexuality was not a mental illness. Despite these researchers’ opinions in 1973,

Science is uncovered origins a lot of things over the centuries and the human created much great inventions and even explored the surface of the moon; however, one question still on everyone’s mind and science may have solved one of greatest mysteries yet which is: how did homosexuality and heterosexuality evolve? Many psychologist, biologist and scientist may agree with sexual orientation is output from a combination of biological, hormonal, environmental and emotional factors and those many factors that influence to a development of human sexual orientation. However, being homosexual or bisexual is not mentally ill or abnormal in certain ways, although sexual minority is part of social problems that makes output from misinformation or prejudicial attitude. Diversity in sexual orientation has been a subject that has been seen in different perspectives by the different people (LeVay, 2010). Today there are the homosexuals, heterosexuals and bisexuals orientated people are forming a part of our society. This paper conduct an overall study of important and strong factors and provides accurate information and explanation for those who want to better understand development of sexual orientation.

Many people now believe the reporting of many popular newspapers and magazines report of the "discovery" of a link between a certain gene and homosexuality, but hasn't it been considered a choice for such a long time? Is homosexuality a choice rather than genetic? To answer this question we'll start off by revealing some myths of homosexuality. The next part will explain the difference between a behavioral trait and a genetic trait. Finally I'll end be unveiling the truth behind the "homosexual gene."

It has long been debated where our sexual orientation comes from, particularly whether its biological or social forces driving these behaviors. In regards to homosexuality and bisexuals, some have argued that it may be a choice that these individuals are making.(Levay 2012: 41)Some have even said it is a mental disorder that one can recover from, but there is plenty of data that says otherwise.(Levay 2012: 41)(Levay 2012: 65) I believe diverse sexual orientations develop in humans due to sex hormones during fetal life, gene influences, and other effects such as birth order influences. I’ve come to this conclusion based on the narrative provided via Dr. Simon LeVay’s book Gay Straight, and the Reason Why, and the research that has been compiled showing strong influences from a multitude or reasons. I will also be looking at a research paper by Francesca Iemmola and Andrea Camperio Ciani, who looked into genetic factors influencing sexual orientation in men. It is clear there are gender differences between men and women, and this is probably one of the strongest indicators that hormones can affect the outcome of variations in gender traits.

what ever decision has been made, it has been done so on the basis of

If the argument of homosexual animals is not convincing enough, one must also consider the possibility of genetics. There is research suggesting that certain genetic markers on the x-chromosome are associated with homosexuality: “Using genetic mapping, the team found that a set of five genetic markers at the tip of the long arm of the X chromosome were identical in 33 of 40 pairs of homosexual brothers” (Journal Watch). This does not positively conclude that a person will be gay if he or she has these markers, but it does suggest that there are genetic factors at play rather than sexuality being merely a choice. Much of this research was done in 1993, and: “The same year, a study of twins found a significantly higher correlation of sexual orientation between identical as opposed to fraternal twins” (Bernstein 34). Two people with the same genetic makeup are more likely to both be gay or both be straight than two people with similar but not quite identical genetics.

Homosexuality is genetic! How can this statement be true? It is indeed true in the precise fact that Romans 3:23 points out, “for all have sinned and fall short of the glory of God,” Humanity has been cursed with being genetically embedded with sin and a sinful nature. The current worldview is that homosexuality and multiple sexual orientations come from nature, and not nurture. This viewpoint is correct in that it is human nature to sin and seek out one’s own selfish desire. However, No one is prescribing a remedy for this sin. “Become sober-minded as you ought, and stop sinning; for some have no knowledge of God. I speak this to your shame.” (1 Corinthians 15:34) What the world has done is celebrated this sin and deceive youth through their much-wanted desire for acceptance and identity. There is a copious amount of research out there, along with world definitions of each orientation, and a call for acceptance of others’ orientations. There is also the other side of the argument and the fundamental truths that come from the word of God. Various resources are available to help youth leaders, teachers, parents and pastors to have a higher understanding of this cultural issue and the solutions and treatments available for youth struggling in this area. Spiritual leaders in the home, church, and schools ought to be prepared to teach on these topics readily, since this world, in which many youth are daily immersed, will readily present its own point of view with utter

The question of what causes some people to be sexually attracted to members of their own gender generates many different answers. In recent years, startling new research (Barinaga, 1993, p.17) has indicated that homosexuality is possibly inherited and determined by biological differences in Brain structure and genes. This study raises an interesting question: If homosexuality is hereditary, is there any basis for societal discrimination against something innate? If it is nature, it is good. If it is good, it should be accepted. A genetic component in sexual orientation would send a message to homosexuals and the society that homosexuality is not a fault, and not the fault of anyone other than nature. Gays and lesbians are born in nature, just like some people who are inherited left-handed gene from their parents.
