Nature Vs. Nurture: Homosexuality, Addictions And Intelligence

Nature vs. Nurture
Homosexuality, Addictions and Intelligence There have always been disputes on whether the decision to be homosexual or heterosexual was based on biological or environmental factors. These disputes are known as the Nature vs. Nurture argument. The two sides argue over how gender is chosen within a person. Based on reproductive organs, sex is easily determined at birth: male or female. Gender, however; is the sexual identity an individual takes on. It is possible for sex and gender to be different. For an example of nurture children who were both born with an injured or damaged reproductive organ, males usually can be raised successfully as females. In order to understand which factor is the deciding factor of a person’s gender, both sides of the case must be fully evaluated. DNA studies which appear to prove that gender is a genetic trait. Researchers have analyzed the makeup of the human brain of homosexuals and heterosexuals seeking a connection between gender and the brains physiology. They found when studying the part of the brain directly related to a persons’ sexual drive, that homosexuals had an enlarged hypothalamus, whereas heterosexuals had a normal one indicating a direct correlation between the
Furthermore, differences in how these phenotypes are surrounded can have an impact on the results of gene discovery efforts. Genetic loci that have been consistently associated with various forms of substance addiction, as well as those that demonstrate relevance to pharmacologic treatment. While the nature vs. nurture debate has raged, is the contribution of interactions between genetics and environment. In reality, "gene expression is environment dependent" and it impossible to obtain pure estimates of genetic vs. environmental contribution - one could not exist without the
