Speciation is an important research area, as it increases biodiversity on Earth. When closely related species with incomplete reproductive isolation expand their distribution after some degree of ...

Researchers from the University of Tsukuba and Ryutsu Keizai University find that patterns of reproductive isolation in a haplodiploid spider mite support the prevailing view of the evolution of ...

In the vast realm of insects, certain beetles, mites, and other insects—including bees, ants, and wasps—use a unique system of sex determination known as haplodiploidy. In this system, the sexual ...

Nuclear and cytoplasmic genomes can coevolve antagonistically or harmoniously to affect fitness. One commonly used test for nuclear–cytoplasmic coadaptation relies on the breakup of coadapted gene ...

The process of speciation has puzzled scientists for decades, but only recently they have they been able to reveal the genetic basis of reproductive isolation. Much emphasis has been on Haldane's rule ...
