A test of the snowball theory for the rate of evolution of hybrid incompatibilities

Abstract

Rolling Snowballs The genetic incompatibilities that separate ongoing speciation events have been hypothesized by the Dobzhansky-Muller model of speciation to snowball—that is, accumulate mutations causing postzygotic isolation at a faster rate than the linear accumulation of mutations. This occurs because of potential deleterious epistatic interactions in hybrids involving two or more interacting genes. Testing QTLs (quantitative trait loci) in seed and pollen sterility between multiple species pairs in the plant group Solanum , Moyle and Nakazato (p. 1521 ) show that hybrid female (seed) sterility accumulates exponentially between increasingly distant species pairs, although not for hybrid male (pollen) sterility. In contrast, loci contributing to differences in other traits show no evidence for nonlinear accumulation over time. Matute et al. (p. 1518 ) come to similar conclusions through the use of deletion mapping in comparisons between two pairs of species of Drosophila . The number of genes causing postzygotic isolation grows as fast as the square of the number of substitutions between two species. Thus, a hybrid snowball effect is found in both plants and animals.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The faster-than-linear accumulation of hybrid incompatibilities with divergence time has been recovered in multiple taxa including Solanum, Drosophila, and Mus musculus.

    “this result has been recovered in multiple taxa: Including Solanum (Moyle and Nakazato 2010; Guerrero et al. 2017), Drosophila (Matute et al. 2010), or Mus musculus (Wang et al. 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
