到目前为止，大多数动物的性别是由基因决定的，因为两性之间存在染色体差异。一个波塞群有两组同源的染色体。另一种性别有这样一套完整的染色体，另一套染色体中有一个或多个胚缺失或被不同类型的染色体所取代。在某些群体中，雄性只有一套单倍体染色体。然而，也有一些群体的性别完全或不完全由遗传决定，但在这些群体中却没有发现两性之间的染色体差异。这些包括所有脊椎动物，除了哺乳动物和鸟类。在库蚊所属的双翅亚目的原始亚目-线虫科中，有些科具有性染色体，有些科则没有。根据WOLF（1941）的综述，在Phrgneiclae，Thaumaleidae，Scatopsidae和Fungiuoridtre中发现了性计时体，而在
N most animals so far studied in which sex is genetically determined I there is a chromosomal difference between the sexes. One ses posse~ s~ es two homologous sets of chromoeomes. The other sex has one such complete set, and another set in which one or more inembrrs are absent or replaced by chromosomes of a different type. In some groups the male has only a haploid chromosome set. There are however a number of groups in which sex is wholly or inainly deteriniiied genetically, but in which no chromosomal diflerences between the sexes have been seen. These include all vertebrates except mammals and birds. In the Nematocera, the primitive suborder of the Diptertr Lo which Culex belongs, some families have sex chromosomes, while others have not. According to the review of WOLF (1941), sex chroniosomes are found in the Phrgneiclae, Thaumaleidae, Scatopsidae, and Fungiuoridtre, while no difference between the sexes has been found in
