Incompatible hybrids

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) … Web1) Low hybrid zygote viability: fails to mature normally and dies during development or has phenotype abnormalities that prevent it from reproducing 2) Low hybrid adult viability: …
