本章的目的是将一些基本生殖参数的经验信息与系统发育假设结合起来，为讨论提供一个进化框架。特别地，对有性物种的潜在遗传系统进行了研究。双二倍体被认为是所有主要螨类的祖先，可能构成了蜱、中柱头目大多数高级类群、前柱头寄生虫、大多数甲螨和许多柱头目的遗传系统。基于支系假说，我们认为单倍二倍体在原柱头亚类群Eupodina和Eleutherengona、无柱头亚类群的几个谱系、短柱头亚类群的一些谱系和中柱头亚类群中至少有两次独立进化。根据客观和间接证据，副单倍体可能在子囊纲进化的早期就出现了，并可能在某些皮囊纲进化中趋同。这也表明，大chelidae的arrhenotoky可能是独立于dermanysso总科和ascoo总科的arrhenotoky，也可能是直接来自于eviphido总科的二倍体。文中还讨论了螨虫的细胞形态及其与生态学的关系。
The aim of this chapter is to merge empirical information on some fundamental reproductive parameters with phylogenetic hypotheses to provide an evolutionary framework for discussion. In particular, the underlying genetic systems of sexual species are examined. Diplodiploidy is considered to be ancestral in all major mite groups, probably constituting the genetic system of ticks, most higher taxa of Mesostigmata, parasitengone Prostigmata, most oribatids and many Astigmata. Based on cladistic hypotheses, it is suggested that haplodiploidy evolved independently in the prostigmatid taxa Eupodina and Eleutherengona, in several lineages of Astigmata, in some lineages of Brachypylina and at least twice in the Mesostigmata. Based on objective and circumstantial evidence, parahaploidy may have appeared early in the evolution of Ascoidea and perhaps convergently in some Dermanyssoidea. It is also suggested that arrhenotoky in Macrochelidae has been derived independently from that in Dermanyssoidea and Ascoidea and perhaps directly from diplodiploidy in the stock of Eviphidoidea. Patterns and ecological correlates of thelytoky in mites are also discussed.
