Evolutionary Genetics of the Anatidae

open access: yesJapanese Journal of Ornithology, 1983
Thirty-one species and subspecies consisting of 169 individuals of the Anatidae were tested with 10 enzyme loci by means of electrophoresis. (1) Intra-specific genetic variation was found only in 6 species. The overall mean heterozygosity value was very low (H=0.003).(2) The mean genetic distance (D) was 0.285 among 13 genera, and 0.016 among 31 ...
