The cells of heterogametic females with ZW sex chromosomes express H-Y or H-W antigen. A hypothesis is formulated to explain why these animals are capable of 'practicing' amphigonia retardata, i.e., delay in actual fertilization of eggs by retaining viable sperm within the oviduct for a considerable time (several months).
具有ZW性染色体的异配雌性动物的细胞表达H-Y或H-W抗原。本文提出了一个假说,以解释为什么这些动物能够“实行”迟缓两性生殖,即在输卵管内将存活的精子保留相当长的时间(几个月)从而延迟卵子的实际受精。
