Document Summary
Simply dividing in half, parent is always female. Growth & development of embryo without fertilization of egg. Di: complete male plant vs. complete female plant. Mono: contains both male and female flowers, flowers are separate. Hermaphrodite: flower contains both male and female parts. Muller"s ratchet: a theory about the evolution of sexual reproduction. Allows more existing alleles within a population. Red queen hypothesis: organisms must constantly adapt, evolve, & proliferate to maintain a reproductive advantage. Less genetic diversity = easier to be wiped out by a parasite. Constant extinction rates caused by coevolution of competing species. Advantage of sexual reproduction to increase genetic diversity. Bird bowers used to attract females for mating. Female birds use bowers to estimate males" age. Younger males are allowed to watch older males build bowers to learn. Males destroy other bowers to improve the chances of being chosen by females. Transfer effect: favoring one trait over another, displacing the latter.
