Cory Baker 12-01-09 Section 448 Perm #: 3851763 Anthropology 005, Introduction to Physical Anthropology Problem Set # 8: Sexual Selection, Evolution of Behavior, and Parent-Offspring Conflict. 1.  In obligately sexual species, there seem to regularly be two morphs that we call male and female.  A.  What selection pressures keep male and females phenotypes similar? The selection pressures that keep male and females phenotypes similar are food, predators and  pathogens. B.  What selection pressures might push male and females phenotypes apart? The selection pressures hat keep male and females phenotypes apart is the female reproductive cycle. C.  What do the phrases fast sex and slow sex mean? Fast sex means a particular sex can produce at a higher rate than the opposite sex. In polygyny, males  have faster reproductive success than females and in polyandry, females have faster reproductive  success than males. Slow sex means particular sex produces at a lower rate than the opposite sex. In polygyny, females  have slower reproductive success than males and in polyandry, males have slower reproductive success
