Genetics and Human Sexuality

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).

Focusing on just natural clarifications of human conduct, the Biological Theory trusts that physiological variables tremendously affect sexual conduct. Scholars regularly take a gander at anomalous hormonal and androgenic levels in the body and cerebrum to depict freak sexual practices as in rising hormones are identified with physical changes that advance sexual excitement, climax, discharge, and other sexual movement. "In spite of the fact that a survey of natural studies indicates clashing results about the relationship between

Human sexuality is a common phrase for all, and anything, pertaining to the feelings and behaviors of sex for the human race. Sexuality has been a topic that has been discussed and studied for as far back as 1000 years B.C. and is still being studied today. As the discussion of sexuality has progressed through history, theories have been created based on research and experiments that scholars have implemented, based on their own perceptions of human behavior. Out of the many theories that pose to explain sexual behavior, Sexuality Now explained ten that are seemed to be the most overlapped, and built off of theories. Of these theories, two that were discussed in the text were the behavioral and sociological theory. These two theories cover some of the basic ideas of what could possibly influence a person’s sexuality.

Human sexuality can be interpreted in many different ideas and understandings. Watching the documentary “Guardians of the Flutes,” I was able to see a different life style than I’m use to but at the same time see many similarities. Both men and women have different roles in their daily lives and their works do not intersect. The Sambia tribe is patriarchal, in which the men have the control or rule, similar to most American house hold; however, that is changing. Understanding the way sex influences or impacts our lives is very important. Not only do humans interact sexually but also many animals. Human sexuality is being able to be comfortable with one to be able to interact with others in a deeper level.

In the article, “Geneticist Says Lesbianism Is Cultural, ‘Not Inherited’: Hamer Claimed Genetic Link for Male Homosexuality,” the author, Joyce Howard Price, examines a controversial research study that was performed by a geneticist with the National Cancer Research Institute, Dean Hamer. Price revealed Hamer’s conclusions of his study which illustrated different reasonings for sexual orientation in men and women. Hamer concluded that “male sexual orientation had many of the characteristics of a genetically influenced trait” (2) but that female homosexuality was rather “a willingness to listen to one’s own heart” (4) and “an openness to new feelings and new experiences.” (4). The author has also included research from other geneticists in

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

Human sexuality is defined as the capability of individuals to experience their sexuality and be able to express themselves as sexual beings (Hyde & DeLameck, 2006). Our interest in this topic is because with time, there has been a change in rules that control human sexual behaviour. The status quo in our contemporary society is much different as compared to an earlier state of conditions, and the change has, as a result, brought the evolvement in human sexuality. People 's view on virginity has changed greatly with a decrease of importance in regards to its preservation. Sexuality is essential to the economic, cultural, social and political organization of society or country. Our sexuality plays a fundamental role in all our lives regardless of age, sex or race. It forms a basic part of our personality and the decisions we make in what we do. One’s sexuality also consumes much of their time through behaviour or thoughts; at times every aspect of our lives seems to revolve around our sexuality. Studying sexuality is very important since human sexuality majorly contributes to social as well as personal problems. A lingering question concerning this topic is to what extent is virginity determined by the status quo and the rules that control human behaviour?

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,

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."

Without having any value judgments on sexual deviancy- the word itself many seem to imply disapproval. Whether it be transvestism, voyeurism, exhibitionism, or sadomasochism, sexual deviancy is by many considered unnatural and inhuman. However these two words 'unnatural and inhuman' is exactly what homosexuality is not. The truth is, sexual deviancy is as much a function of biology and as much a product of nature - as the orthodox sexuality which society accepts as 'natural'. Of course some adult sexual orientation is caused by early social conditioning, but through research and hard evidence, scientists have found that sex, gender and sexual orientation are all

Throughout history it is evident that human sexuality changes do to religious, governmental and societal influences. The perception of human sexuality has gone through many changes such as being very open and unlabeled activity; to being very “conservative” and a topic that shouldn’t be talked about in public or at all. In any case, human sexuality has always been a topic of interest because humans are sexual beings who want to understand the consciousness of themselves as male or female and see their personal response when encountered in erotic experiences with other individuals. Unlike many other species whose sexual force is strictly for reproduction, human’s sexual drive seems to be driven by many factors that intertwine with each other which leads to very different outcomes. Do to these obscure human emotions and personal gratification, sex is always shown every culture’s art, literature, social norms, and laws.

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.
