In the case of the Bombina frogs, the evidence that hybrid zone stability is occurring was the consistent pattern from annual to annual of declining frequency of yellow-bellied toad alleles with distance from the edge of their range. This is a clear evidence that hybridization is taking place yearly in the Bombina frogs.
