# 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.

## Key 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.
