The common cuckoo is divided into host-specific races (gentes). Females of each race lay a distinctive egg type that tends to match the host's eggs. It was provided genetic evidence that gentes restricted to female lineages from the fact that there is differentiation between gentes in maternally inherited mitochondrial DNA, but not in microsatellite loci of nuclear DNA. This supports recent behavioural evidence that female, but not male, common cuckoos specialize on a particular host, and is consistent with the possibility that genes affecting cuckoo egg type are located on the female-specific W sex chromosome. Our results in Japan also supported these ideas, but the host races are not so clear in Japan, due to colonization by separated ancestral lineages.

杜鹃根据寄主不同分为不同的种族（氏族）。每个种族的雌性都会产下一种独特的卵类型，这些卵往往与宿主的卵相匹配。遗传证据表明，氏族仅限于女性谱系，因为氏族之间在母系遗传的线粒体 DNA 中存在分化，但在核 DNA 的微卫星位点中却没有差异。这支持了最近的行为证据，即雌性而非雄性普通杜鹃专门针对特定宿主，并且与影响杜鹃卵类型的基因位于雌性特异性 W 性染色体上的可能性一致。我们在日本的结果也支持了这些想法，但由于不同祖先谱系的殖民化，日本的宿主种族并不那么明确。
