Abstract
Drosophila nasuta nasuta (2n=8) andDrosophila nasuta albomicana (2n=6), a pair of cross fertile races have conspicuous karyotypic divergence and symptoms of postmating isolating mechanisms. Hybridization of these races followed by hybrid maintenance and hybrid recombination has resulted in the evolution of two novel races with new combinations of parental chromosomes referred to as Cytoraces I and II and this has illustrated an interesting aspect of karyotypic differentiation under laboratory conditions.
