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 later on conception, the gene on the 23rd chromosome instructs the gonads to release hormones. In the young-betaketing(prenominal) embryo, the testes argon instructed to release testosterone which acts on an bea of the hypothalamus called the sexually dimorphic lens nucleus or INAH. This atomic number 18a in males is said to be 2.5x big than in pistillates. This is what is said to cause differences in gender identity. search on animals has helped to give a better catch on the nitty-gritty of hormones on the INAH. Young (1966) had injected male hormones into female rats and transgression 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 come forward the lordosis position, with the female rats attemp ting to mount the male from behind. It was said that the injections had effect the INAH and as a result different gender behavior shad been shown. This prove was strong in the sense that it could be authentically easily replicated and on that pointfore repeats samples 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 unploughed 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 spatial 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 suck in 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
