Abstract
Muscovy ducks (Cairina moschata) are one of the poultry species that contributes significantly to protein consumption around the world as they complement eggs and meat supply from chicken in terms of availability and affordability, especially among the resource poor farmers in developing nations. In Nigeria, Muscovy duck is an integral part of poultry sector that needs more attention for higher productivity because of their adaptability and hardy nature. The genetic diversity, polymorphism and relationship between some Muscovy duck populations in Nigeria were analyzed using mitochondrial cytochrome b gene (Mt CYTB). The results showed a total of 40 polymorphic sites consisting of 19 singletons variables with 42 mutations. The 72 cytochrome b sequences obtained were assigned to 17 distinct haplotypes with low diversity (0.439) among the populations studied. Phylogenetic analysis showed close clustering of monophyletic clade within some populations across the locations with the exception of a few populations (BON 10, BON 20 and ADE 11) that show a distant relationship of polyphyletic clustering. These findings inferred that the genetic diversity within the Muscovy ducks from the study area is low, there were variants forms of specific DNA sequence, and only few populations of the Muscovy ducks are from more than one common ancestor concerning mitochondrial cytochrome b gene. Therefore, selective mating of Nigerian Muscovy ducks and the use of other types of markers for diversity study are recommended for rapid genetic gain in any breeding program designed for their improvement.
