WebFeb 26, 2015 · We found that parentally biased expression was perturbed to a similar degree in both A. thaliana hybrids for PHERES1, HDG3, and six other normally paternally expressed genes. We propose that early genome remodeling and loss of imprinting of seed development genes induces lethality in both compatible and 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) …
