Unexpected variability of gametogenic pathways and interspecific chromosomal leakage in Pelophylax esculentus hybrids.
Hybridization is common among animals and plants, but often leads to sterility due to improper chromosome pairing. Some hybrids overcome sterility through modified gametogenesis, enabling clonal or hemiclonal reproduction. In water frog hybrids from the Pelophylax esculentus complex, hybridogenesis typically ensures he...
