Mapping and characterization of a 'speciation gene' in Drosophila.

Genetical research - 1 Apr 1992

Orr H A

Abstract excerpt

Almost nothing is known about the identity of the genes causing reproductive isolation between species. As a first step towards molecular isolation of a 'speciation gene', I mapped and partly characterized a gene causing hybrid male sterility in Drosophila. This analysis shows that sterility of D. melanogaster males who carry the 'dot' fourth chromosome from D. simulans is due entirely to a very small region of...
