[选择] Parthenogenesis Competition Genetic drift Meiosis Sexual reproduction Adaptation Gene flow is a great adaptive strategy for stable environments, while [选择] meiosis competition sexual reproduction asexual reproduction recombination adaptation parthenogenesis is a better adaptive strategy for dynamic environments.  This is because stable environments allow for [选择] mutations lower population adaptation gene flow less genetic diversity evolution more genetic diversity because a species is already well-adapted.  But dynamic environments require [选择] greater genetic diversity mutations parthenogenesis evolution adaptation mitosis less genetic diversity to allow for faster [选择] population decrease adaptation sexual reproduction mutations natural selection population increase gene flow to changing conditions.  Greater [选择] fitness reproductive success genetic diversity mutation rate extinction gene flow genetic similarity is the result of [选择] gene flow, when traits are passed down from one generation to the next the evolution of sexually reproducing species mitosis, when cellular division occurs during sexual reproduction genetic drift and genetic bottlenecking meiosis and recombination, when gametes are made .
