Nature vs. Nurture EssayHomo rideuality, Addictions and IntelligenceThere establish always been disputes on whether the decision to be homosexual or heterosexual was based on biological or surroundingsal factors. These disputes argon known as the Nature vs. Nurture argument. The two sides argue everywhere how sexual urge is chosen within a person. Based on fruitful organs, sex is easily contumacious at birth male or female. Gender, however is the sexual identity an individual homecomings on. It is possible for sex and sex to be different.For an example of nurture baby birdren who were both born with an injured or damaged reproductive organ, males usually cannister be raised success amply as females. In order to understand which factor is the deciding factor of a persons gender, both sides of the case must be fully evaluated. DNA studies which appear to prove that gender is a cistrontic trait. Researchers have analyzed the makeup of the valet de chambre promontory of homosexuals and heterosexuals seeking a connection between gender and the brains physiology.They found when studying the part of the brain checkly related to a persons sexual drive, that homosexuals had an enlarged hypothalamus, whereas heterosexuals had a normal one indicating a direct correlation between the brain and gender selections (AllPsych).In researching DNAs role in gender identity, some scientist have identified the gene that determines a persons sexual preference. Although there are bestrideing evidence of the existence of a gay gene, the opposition denies the existence (AllPsych). People in certify of the Nurture argument claim that is an individual conscious or subconscious decision as to his or her gender identify. While many claim that people may tick their sexual orientation, their brain, and not the otherwise way around are actually controlling them.A person DNA and brain physiology control sexual preference which may be associated in the amygdale of the li mbic system (Pscyhsmart). When scientist cast scum baged the rats, stopping the excogitation of androgen, the male rats became submissive. When the androgen was given to the female rats, they began to display masculine behaviors. This experiment resulted in the male rat being submissive and allowing the female rat tomount the male, unlike the normal male rat that would mount the female when engaging in reproduction ( Lippa 102).Similar to humans, if male do not have kosher balance of hormones with his body, he may show feminine traits. These hormones are a biological aspect of gender that affects the decision to be homosexual or heterosexual. On the other hand, for the purpose of this discussion, addiction can take many forms, including not only substance use disorders, but also pathologic gambling, bulimia, and a force of other disorders. Dependency, abuse, and addiction are used relatively interchangeably however, there is ongoing debate within the field regarding the best term inology.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 indicate relevance to pharmacologic treatment. While the nature vs. nurture debate has raged, is the share 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 with away the other.The environment a child experiences is partly a consequence of the childs genes as well as external factors. To some extent a person seeks out and take a leaks his or her environment. If she is of a mechanical bent she practices mechanical skills if a bookworm, she seeks out books. Thus genes may create an appetite rather than an aptitude. Remember that the high heritability of defraud-sightedness is acc ounted for not just by the heritability of a gene for short sightedness but by the heritability of literate habits.Conversely, on the discussion of intelligence, there are three facts nearly the transmission of intelligence that virtually everyone seems to accept 1. Both heredity and environment contribute to intelligence. 2. Heredity and environment interact in various ways.3. Extremely poor as well as highly enriched environments can interfere with the realization of a persons intelligence, regardless of the persons heredity (Sternberg Grigorenko, 1997, p.xi). Intelligence that appears to relate to ability to reason abstractly, to tally and to adapt. In closing, homosexuality, addictions and intelligence have reliablestatistical relationships with important social phenomena, but they are a limited tool for deciding what to make of any given individual. As stated by Ridley, scram Nature has plainly not entrusted our genetic capacities to the blind fate of a gene or genes she ga ve us parents, learning, language, culture and education to program ourselves with.WORKS CITEDJohnson, Ryan D.
