Genetics and Human Sexuality - 1320 Words

Human sexuality plays a major role in everyones life. Regardless, whether we are young or old, man or woman, American or Japanese, it is an integral part of what we do and who we are as a human species. Next to sleeping and eating, it seems that it is one of the most important drives we have to deal with as humans. That is, it takes up so much of our time in thought and behavior that it sometimes seems that every facet of our life revolves around this to a certain extent. Human sexual behavior is different from the sexual behavior of other animals, in that, it seems to be governed by a variety and interplay of different factors. That is, while lower animals or species are driven by a force to reproduce and therefore partake in sexual†¦show more content†¦In the second volume of The Variation, written by Charles Darwin, to prove his theory of evolution he had to explain the notion of natural selection and how genetic variations play a vital role in this process. Which brings up the second principle of evolution which is that the variations must be passed on genetically. Numerous identical twin case studies have shown that the hereditary of homosexuality is not strictly a genetic linkage, because there are many pairs of identical twins who have differing sexualities. Scientists from the National Institute for Mathematical and Biological Synthesis say homosexuality seems to have an epigenetic, not a genetic link. Epigenetic is the study of heritable changes in gene activity that are not caused by changes in the DNA sequence or genotypes, but rather phenotypes. Homosexual attraction has been said to be passed along in families, there is no proof of that, but leading researchers presume a genetic underpinning of sexual preference is lurking. While genes hold the instructions in the DNA, epi-marks direct how those instructions are carried out. The act of sexual activity among homosexual does not allow genetic traits to pass forth through reproduction which r equires semenShow MoreRelatedEssay on The Details of Human Sexuality and Society1246 Words   |  5 PagesThis is a definition of from someone who has studied human sexuality †human sexuality is the way in which we experience and express ourselves as sexual beings (Rathus et al., 1993). There are many factors that help develop our sexuality, arguably one of the most important, is our actual gender. Whether, I am a male or female will likely have a major influence on the development of my individual sexuality.

Nurture : Psychology And Biology1449 Words   |  6 Pages Nature vs. Nurture is one of the most prevalent theories in psychology and biology; scientists previously believed that personality traits were derived from either genetics or environmental elements, but more recently have concluded that both factors play a role in the expression of genes. However, the influences of genetics and environmental factors on sexual orientation is still a controversial topic which is currently being discussed in both psychological and biological debates. While many researchersRead MoreGenetic Determinism of Human Character Essay640 Words   |  3 PagesHuman character and behaviour are not only shaped by the genes that encompass the individual’s genotype. Human character comprising mainly of personality, sexuality, morality and intelligence are the products of genetic determinism as well as external environmental factors. â€Å"Single genes can have surprisingly strong influences on particular aspects of behaviour.† (Frank., 2009) Genes build the phenotype of humans as well as the underlying genotype.

Studies showed that there were genetic factors linked to influencing sexual orientation in males before they were born by increasing the female reproductive capacity in mothers during multiple births.

Sexual assimilation is a physiological attribute that exhibit one of the greatest scopes of sexual distinction, given that 90-97% of human beings of one sex demonstrate an appeal that is dissimilar from that of the alternate gender (Slife, 2013, p. 36).

Whether someone is homosexual or heterosexual is thus also considered to be a crucial aspect of who he or she is as a human being.

With homosexuality growing, sexual orientation has been a major discussion in the world throughout the last decade. Some have argued that it has to do with genetics, and some say that it has to do with the environment. This is known as the long-term controversy of nature versus nurture.

Lucal, in his article focuses on the building and preservation of boxes and limits with respect to sex, gender and sexuality. In the society, these boxes and their limits rest on a multiplicity of assumptions. The first supposition is that there are two sex’s genders, and sexualities. Everyone is male or a female, feminine or masculine, heterosexual or homosexual but no one can be both. This supposition of sex believes the truth of substantial difference
