Document Summary

Infancy + children: gender typing: how children acquire their knowledge about gender + how they develop their gender- related personality characteristics, preferences, skills, behaviours + self-concepts, prenatal period: time before birth = sex organs develop. 23 chromosomes from each parent > 23 chromosome pairs = 22 determine physiological + psychological characteristics. 23rd = determines sex: before 6 weeks after conception = female + male embryos = identical. Each fetus has two sets of primitive internal reproductive systems. >male system = wol an ducts: gonads: sex glands = look similar after rst weeks after conception. Y chromosome sends message so that gonad knows to develop into prostate + testes (6 weeks after) Xx chromosome sends message so that gonad knows to develop female ovaries (8-10 weeks after) >m"s testes secrete 2 hormones: a) mullerian inhibiting hormone = shrinks the female mullerian ducts: androgen: high levels of this hormone encourage growth + development of wol an ducts.
