Linkage analysis of the transferrin, albumin, and hemoglobin loci in leopard frogs.
Transferrin was found to be monomorphic in a sample of 20 wild-caught Rana pipiens and 20 R. blairi. Albumin was monomorphic in R. Blairi, but one of the 20 R. pipiens was heterozygous at the albumin locus. The homologous proteins of the two species differ in their mobility. Both parental proteins are represented in hybrids. Backcross offspring exhibit no significant deviation from the expected normal Mendelian ratios. Linkage data suggest a weak linkage between the albumin and transferrin loci with neither of them being linked with the hemoglobin linkage group.
