Biological Explanations For Gender Development

The biological explanation for the development of gender identity, lies in the in the size of the hypothalamus in the brain and prenatal development. Between 4-8 weeks afterwards conception, the gene on the 23rd chromosome instructs the gonads to release hormones. In the young-be perk upting(prenominal) embryo, the testes argon instructed to release testosterone which acts on an ara of the hypothalamus called the sexually dimorphic nub or INAH. This ara in males is said to be 2.5x big than in pistillates. This is what is said to cause differences in gender identity. research on animals has helped to give a better catch on the issue of hormones on the INAH. Young (1966) had injected male hormones into female rats and wrong-doing versa during a critical stage in archaeozoic development. He found that the mating positions for the rats had been reversed and that the male rats had pick show up the lordosis position, with the female rats attempting to mount the male from b ehind. It was said that the injections had effect the INAH and as a result different gender conduct shad been shown. This prove was strong in the sense that it could be in truth easily replicated and on that pointfore repeats investigates could be set up in order to ensure the validity of the results.

It was withal a controlled experiment which allowed manipulation of the independent variable and the effects of extraneous variables were unbroken limited. Additionally, the use of rats was another strength to the experiment as it is comparatively easier to experiment on rats than humans. The findings had also reinforced the nature spacial relation of the nature-nurture debate in regards to gender development. However ! there are many issues that compromise the strength of the research for example, generalizability in regards to compare rats so closely to humans. As rats and humans are really different species, it is a big statement to impound that they bat in exactly the same way. There are also ethical concerns in regards to this research with regards to the...If you want to get a full essay, order it on our website: OrderEssay.net
