Tetraploid forms as a result of hybridization at coexistence of clonal-bisexual spined loaches Cobitis

Annotation

We investigated the meiosis of tetraploid males of spined loaches Cobitis from the unisexual-bisexual complex of Volga Basin’s river. Incomplete genetic compatibility of the forms, involved in the emergence of such males, leads to an imbalance of their gametes and the absence of potential for reproduction. Apparently the stable forms in this complex Cobitis exist in equilibrium, the spontaneously occurring tetraploid individual mark unique “hybrid zone”.

Keywords

bisexual-clonal complexes; hybridization; meiosis; genus Cobitis.
