Asymmetric hybridization of roach Rutilus rutilus and common bream Abramis brama in controlled backcrosses: Genetic and morphological patterns

open access: yesBiosystems Diversity, 2020
In most cases in natural environments, hybrids of roach Rutilus rutilus L. and bream Abramis brama L. possess mitochondrial DNA of bream. Presumably, the genetic basis for unidirectional hybridization of roach and bream is the high level of divergence in
