All plant and animal species arise by speciation — the evolutionary splitting of one species
into two reproductively incompatible species. But until recently our understanding of the …

Speciation—the splitting of one species into two—occurs by the evolution of any of several
forms of reproductive isolation between taxa, including the intrinsic sterility and inviability of …

The three species of the Drosophila simulans clade—the cosmopolitan species, D. simulans,
and the two island endemic species, D. mauritiana and D. sechellia—are important models …

Two empirical rules suggest that sex chromosomes play a special role in speciation. The
first is Haldane's rule – the preferential sterility and inviability of species hybrids of the …

I present patterns characterizing the evolution of intrinsic postzygotic isolation in Lepidoptera
by analyzing data from the literature on genetic distance, strength of hybrid sterility and …

Meiotic drivers are genetic variants that selfishly manipulate the production of gametes to
increase their own rate of transmission, often to the detriment of the rest of the genome and the …

Postzygotic reproductive isolation is characterized by two striking empirical patterns. The
first is Haldane's rule—the preferential inviability or sterility of species hybrids of the …

In multicellular organisms, telomerase is required to maintain telomere length in the germline
but is dispensable in the soma. Mice, for example, express telomerase in somatic and …

New species arise as reproductive isolation evolves between diverging populations. Here
we review recent work in the genetics of postzygotic reproductive isolation—the sterility and …

Segregation Distorter (SD) is an autosomal meiotic drive gene complex found worldwide in
natural populations of Drosophila melanogaster. During spermatogenesis, SD induces …
