dcterms:description
Comparisons of morphology, nuclear gene sequencing and microsatellites were used to identify 19 hybrids between the related species Cottus poecilopus and Cottus gobio in three rivers of the Odra River drainage basin. All hybrids were the results of backcrossing and no F1 generation hybrid was found. The resulting progeny are fertile and continue in backcrossing with parental conspecifics. A high representation of backcrosses appears to indicate a lack of reproduction barriers within the hybridization process. It was impossible to differentiate individual back-cross categories on the sole basis of six loci. Mitochondrial haplotypes indicate that this is not a one-way process. In our study, hybridization was asymmetrical in favour of Cottus poecilopus.
