Document Summary

Estradiol and progesterone: male = wolffian duct prevailed. Anti- mullerian hormone (kills mullerian duct) & androgens: genetic disorders of differentiation: Androgen insensitivity (xy female): lack of androgen receptors external female, but no internal female parts. Persistent, mullerian duct syndrome: male with both male and female internal organs doesn"t produce anti-mullerian hormone or receptor. Congenital adrenal hyperplasia: exposure of female fetus to androgens (can produce an enlarged clitoris, fused labia and tomboyish behaviour. Turner"s syndrome (x0 female): underdeveloped ovaries; infertile. Kleinfelter"s syndrome (xxy male): underdeveloped testis; infertile. Super males (xyy): more physically active as children; slower emotional development. Super females (xxx): passive and quiet infants: forms of replication: Fission: bacteria and lower eukaryotes; genetically identical progeny. Doesn"t optimally transmit the best parent"s genes: arguments in favour of sex: You get the best of both worlds (ideally) Creates genetic variety: pheromones: chemical an animal releases to attract a mate.
