Document Summary
Copulation, reproduction, recombination, maleness/femaleness (gender: all related to sex. Note: mutation creates new alleles, sex creates different combinations of alleles. Is it possible to predict when an individual should change sexes? (optimal age, etc. ) M > f (protandry) - when the arrows cross, this is the optimal time for sex change. F > m (protogyny) - when the arrows cross, this is the optimal time for sex change. Baboons - daughters inherit mothers social status overproduce daughters when strong, overproduce sons when weak. Sexual vs asexual reproduction in animals: more animals produce sexually instead of asexually, other types of eukaryotes will show different patterns - why is sexual reproduction high in animals but not other organisms. Recombination speeds up adaptive evolution (combines helpful mutations: sexual recombination: allows two or more advantageous mutations to occur together in the same individual more quickly, clonal interference: without recombinations,
