Comment on “A Test of the Snowball Theory for the Rate of Evolution of Hybrid Incompatibilities”

Daniel A. Barbash

<jats:p> Matute <jats:italic>et al</jats:italic> . (Reports, 17 September 2010, p. 1518) tested the theory that the number of genes involved in hybrid incompatibility increases faster than linearly. However, the method they used is inappropriate because it detects genes that are haploinsufficient in a hybrid background but that would not contribute to lethality in wild-type hybrids, thus overestimating the frequency of hybrid inviability. </jats:p>

Response to Comment on “A Test of the Snowball Theory for the Rate of Evolution of Hybrid Incompatibilities”

Daniel R. Matute; David A. Turissini; Jerry A. Coyne

<jats:p>Barbash claims that deficiency mapping of inviability regions cannot distinguish hybrid lethality from haploinsufficiency, the phenomenon whereby a single functional copy of a gene cannot maintain normal function in a hybrid genetic background. Although we acknowledge that his hypothesis deserves careful experimental testing, we argue against his conclusions and provide evidence that our methodology is suitable to study the evolution of Dobzhansky-Muller incompatibilities.</jats:p>
