Hybridization among diverging lineages is common in nature. Genomic data provide a
special opportunity to characterize the history of hybridization and the genetic basis of …

Introgression, the incorporation of genetic material from one (sub) species into the gene pool
of another by means of hybridization and backcrossing, is a common phenomenon in birds …

The house mouse, Mus musculus, was established in the early 1900s as one of the first
genetic model organisms owing to its short generation time, comparatively large litters, ease …

Research into differences in introgression potential among autosomal, sex-linked, and
mtDNA loci is an active field of inquiry in both model and non-model species. At the same …

Polar bears are an arctic, marine adapted species that is closely related to brown bears.
Genome analyses have shown that polar bears are distinct and genetically homogeneous in …

General parameters of selection, such as the frequency and strength of positive selection in
natural populations or the role of introgression, are still insufficiently understood. The house …

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 …

Hybrid zones are established where two divergent populations meet and interbreed, but
experience some reproductive isolation. If one population expands its range at the expense …

Speciation typically involves a stage in which species can still exchange genetic material.
Interspecific gene flow is facilitated by the hybrid zones that such species establish upon …

Understanding recent speciation history requires merging phylogenetic and population
genetics approaches, taking into account the persistence of ancestral polymorphism and …
