Many animals can adjust the sex ratio of their offspring according to their parental ability to invest. In spider mites, larger eggs are likely to be fertilized and produce diploid females, whereas smaller eggs produce haploid males.
许多动物可以根据自身的亲代投资能力来调节后代的性别比例。在蜘蛛螨中,较大的卵更有可能受精并产生二倍体雌性,而较小的卵则产生单倍体雄性。
