Incompatible hybrids
WebJul 23, 2024 · We examine here the detailed mechanistic basis of hybrid incompatibilities between two allopatric lineages, for a genotype-phenotype map of developmental system drift under stabilising selection, where an organismal phenotype is conserved, but the underlying molecular phenotypes and genotype can drift. 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.
