摘要: An extrachromosomal factor, termed son-killer (sk), affects the sex ratio in a parasitoid wasp, Nasonia (=Mormoniella ) vitripennis. The factor is maternally transmitted and alters secondary of an infected female through mortality approximately 80% male embryos. No effect on primary (zygotic) observed. Ninety-five percent daughters inherit son-killer. can also be contagiously when progeny uninfected females develop simultaneously single host. In newly strains, effects are equivalent to those original.
