Document Summary

Sexy times: examples of genetic exchange/ recombination without reproduction, and of reproduction without genetic exchange/ recombination. Asexual- reproduction without recombination, i. e. bacteria, via binary fission. Obligately asexual- every individual is born female, cannot reproduce sexually, and must produce asexually. i. e. amazon mollies, must engage in courtship with male of similar species, pseudo mating. Therefore asexual reproduction must have occurred very recently. Pseudo mating is a result of evolutionary holdover. Facultatively sexual vs. asexual- when things are good, they reproduce asexually. When things are not good, they reproduce sexually. i. e. some trees: how recombination contributes to population genetic variation. The offspring are distinct from either parent (usually) and each other: meanings of monoecious, dioecious. Many flowering plants have male and female function within the same individual. Every individual is both male and fe(cid:373)ale (cid:862)o(cid:374)e house(cid:863).
