Genetic differentiation and phylogenetic relationships among greek silurus glanis and silurus aristotelis (Pisces, siluridae) populations, assessed by PCR-RFLP analysis of mitochondrial DNA segments

abstract：:Although allelic variants at a locus usually are expressed either dominantly or co-dominantly, there are many cases when a gene is dominantly expressed in some individuals and co-dominantly in others. We present a maximum-likelihood procedure for allele frequency estimation in such situations of "incomplete" co-domina...

One such hybrid zone is formed by the fire-bellied toads Bombina bombina and B. variegata (Anura: Discoglossidae)....
