Islands in the Genome Promote Speciation

TL;DR

The study finds specific genome regions in hybridizing mosquitoes that may cause reproductive isolation and drive speciation.

Contribution

Identifies three small genomic regions linked to reproductive isolation in hybridizing mosquitoes.

Findings

Three small genomic regions differ between hybridizing mosquito forms.

These regions likely contain genes responsible for reproductive isolation.

The findings suggest these genomic 'islands' promote speciation.

Abstract

Using DNA microarrays, the authors identify three small regions of the genome that differ between two forms of hybridizing mosquitoes-regions that are likely to contain the genes responsible for reproductive isolation.
