Studies of a hybrid zone between two house mouse subspecies (Mus musculus musculus
and M. m. domesticus) along with studies using laboratory crosses reveal a large role for the …

The Dobzhansky-Muller model of incompatibilities explains reproductive isolation between
species by incorrect epistatic interactions. Although the mechanisms of speciation are of …

The house mouse hybrid zone (HMHZ) is a species barrier thought to be maintained by a
balance between dispersal and natural selection against hybrids. While the HMHZ is …

Hybrid sterility as a postzygotic reproductive isolation mechanism has been studied for over
80 years, yet the first identifications of hybrid sterility genes in Drosophila and mouse are …

Comparative genetic mapping provides insights into the evolution of the reproductive
barriers that separate closely related species. This approach has been used to document …

Despite the long-term study of the house mouse hybrid zone in Europe knowledge of its
course in some areas is still rather vague. Comparisons of different portions of the zone …

Hybrid sterility in the heterogametic sex is a common feature of speciation in animals. In
house mice, the contribution of the Mus musculus musculus X chromosome to hybrid male …

Studies of a hybrid zone between two house mouse subspecies (Mus musculus musculus
and M. m. domesticus) along with studies using laboratory crosses reveal a large role for the …

Speciation has occurred countless times throughout history, and yet the genetic
mechanisms that lead to speciation are still missing pieces. Here, we describe the genetics …
