Table 1 The nine homospecific crosses and seven different interspecific hybrid crosses used to measure transgressive segregation with their geographical origin and the number of families per cross type.

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