I found this video very helpful in trying to understand gender determination with a biological mindset. David Page teaches biology and genetics at MIT. His current research focuses on why the Y chromosome is significantly different than all the other chromosomes in the genome. He is interested in why it carries significantly less genes than the X chromosome. The SRY gene (sex determining region on the Y chromosome) was mentioned in some of the required readings for this week. Its presence instructs other genes to make a testis, but then the gene disappears and is not seen again. What are you thoughts on sex chromosomes in relation to sexual identity and sexual preference? The sex hormones are produced by the ovaries or the testes. These hormones (testosterone and estrogen) play an important role in masculizing or feminizing other parts of the body. Do you think different levels of the hormones is a component of determining gender? Do you think if a person with XY chromosomes that has AIS (Androgen Insensitivity Syndrome), has female genitalia and a female typical body is a woman or man? Why? Do chromosomes or physical appearance play a bigger role in determining gender?
