Hybridization dynamics between sympatric species of trout: loss of reproductive isolation.

Journal of evolutionary biology - 1 Sept 2005

Bettles C M, Docker M F, Dufour B, Heath D D

Abstract excerpt

Although reinforcement should enhance reproductive barriers in sympatric species, sympatric trout species do hybridize. Using mitochondrial and nuclear species markers, we investigated hybridization directionality, hybrid mating biases, and selection against hybrids in 13 sympatric cut-throat and rainbow trout populations on Vancouver Island, Canada. Approximately 50% of the genotyped fish were hybrid (F1 or...
