Genetics/ Hormones Flashcards
What did gorse find
Male rats had a sexually dimorphic nucleus that was twice the size of a females
What did Dreisen and Ral find
The corpus coliseum is larger in females
What did young find
Female monkeys exposed to testosterone had more rough play
What did Erhardt and money find
pregnant women who were exposed to the wrong hormones had tomboy girls and non athletic males
What does the case of David Reimer show
he was bought up a female and resorted to being male so biology plays a part
What did Diamond find
Rabies who were injected with testosterone has female babies with male genitals
What are the main IDA points for this theory
Methodological issues of using animal studies
Ignores the role of nurture
outline the role of genetics
there are 23 pairs of chromosomes,
there are 2 types of sex chromosomes (X and Y),
at 6 weeks differentiation of genitalia occurs,
Y triggers synthesis of HY androgen which leads to the development of testes
outline the role of hormones
the testes produce testosterone which is part of the male reproductive system,
the testosterone makes the right side of males brains thicker hence they are more aggressive,
females therefore have a thicker left so they are better at verbal tasks,
AIS occurs when a genetic male is insensitive to effects of testosterone
