Resumo(s)
The hybridogenetic fish complex Squalius
alburnoides comprises diploid males with non-hybrid
nuclear genomes and several hybrid forms varying in
ploidy and relative proportions of the parental genomes. In
this paper, we present evidence that in captivity females
prefer to mate with non-hybrid males. We suggest that
female choice combined with different ecological requirements
of hybrid and non-hybrid males may explain the
extreme variation in the relative abundance of male types
among drainages.
