Carbonic anhydrase isoenzymes in nine troops of Kenya baboons, Papio cynocephalus (Linnaeus 1766)

The distributions of alleles at the carbonic anhydrase I (CA I = CA B) and carbonic anhydrase II (CA II = CA C) loci in nine troops of Papio cynocephalus were determined. Two alleles were found at the CA I locus, and three at the CA II locus; the frequencies were: CA I^a = 0.856; CA I^b = 0.144; CA II^a = 0.784; CA II^b = 0.209; CA II^c = 0.007. Results of tests for Hardy-Weinberg equilibrium, homogeneity tests, and calculations of migration rates were used in support of the interpretation that migration and genetic drift may affect the distribution of alleles at the CA I locus and that selection is the process responsible for the distribution of alleles at the CA II locus.
