WebMay 27, 2016 · Dobzhansky–Muller (D–M) Model The D–M model of hybrid incompatibility ( Dobzhansky 1936; Muller 1939) can be described as follows. Start with an ancestral population with the genotype AABB at 2 loci.

WebWe investigate the conditions for the origin and maintenance of postzygotic isolation barriers, so called (Bateson-)Dobzhansky-Muller incompatibilities or DMIs, among populations that are connected by gene flow. Specifically, we compare the relative stability of pairwise DMIs among autosomes, X chromosomes, and mitochondrial genes. WebSep 17, 2010 · The Dobzhansky-Muller model ( 3, 6 – 9) has produced empirically testable predictions including the “snowball effect”—the number of DMIs accumulating between lineages is expected to “snowball” (increase faster than linearly) with increasing time since lineage divergence ( 3, 6 ).

WebSep 7, 2024 · The Dobzhansky-Muller model is arguably the most widely accepted model to explain the buildup of intrinsic postzygotic isolation in allopatric populations, and many examples of DMIs have been identified empirically [ 29 – 36 ]. WebThe first major breakthrough in the genetic basis of hybrid incompatibility is the Dobzhansky-Muller model, a combination of findings by Theodosius Dobzhansky and Joseph Muller between 1937 and 1942. The model provides an explanation as to why a negative fitness effect like hybrid incompatibility is not selected against.
