单词	assortative
释义	assortative /əˈsɔːtətɪv / adjective Denoting or involving the preferential mating of animals or marriage between people with similar characteristics: assortative mating... Fruit flies have served as a prime model system in research on the effect of mate choice and assortative mating on speciation. Mating may thus be assortative as females mate selectively with males of the same vocal background, discouraging gene migration. Condition-dependent preferences will emerge in both sexes as a result and presumably will combine to make mating even more strongly assortative.
