Genetic Distance and Hybridization of Black Ducks and Mallards : A Morph of a Different Color ?

Ankney et aL (I 986) assayed genetic variation within and among North American populations of Mallards (Anas platyrhynchos) and American Black Ducks (A. rubripes). They concluded that their "genetic data do not support even subspecific status for the Black Duck." Morgan et al. (1976) also reported that biochemical characteristics of these two species were… CONTINUE READING
