WebEvolution of Hybrid Incompatibilities. It is widely believed that the normal course of evolution within isolated or semi-isolated populations gives rise to genetic incompatibilities that … WebHybrid inviability in Drosophila melanogaster/D. simulans hybrids results from incompatible interactions between two genes, Hmr and Lhr.Several mutations have been fixed in the D. melanogaster Hmr gene, while other mutations have been fixed in the D. simulans Lhr gene.This finding supports: (a) Haldane’s rule (b) Vicariant allopatric speciation (c) …

WebIncompatible cytoplasm. In a few cases, embryo development may be blocked by an incompatibility between the cytoplasms of the species used as female and the genome of the species used as male. Such an interaction more generally, leads to hybrid weakness and male sterility in the hybrids. In a few cases, embryo development may also be prevented.
