Phenotypic novelty in experimental hybrids is predicted by the genetic distance between species of cichlid fish.

BMC evolutionary biology - 4 Dec 2009

Stelkens Rike B, Schmid Corinne, Selz Oliver, Seehausen Ole

Abstract excerpt

BACKGROUND: Transgressive segregation describes the occurrence of novel phenotypes in hybrids with extreme trait values not observed in either parental species. A previously experimentally untested prediction is that the amount of transgression increases with the genetic distance between hybridizing species. This follows from QTL studies suggesting that transgression is most commonly due to complementary gene...
