The Genetic Variation and Distance of Local Duck in West Sumatera

Abstract

The basic difference between the qualitative and quantitative characteristics were involves a number of genes that contribute to phenotypic variability. For conservation purpose, identification of phenotype and genetic variations for future development is required. The aims of this research are to determine: (1) heterozygosity value and (2) genetic distance of three population local duck in West Sumatera (Pitalah, Kamang and Bayang). For measurement of heterozygosity and genetic distance, 25 ducks were selected randomly from each population group for DNA analysis by using DNA microsatellite markers which used Popgene32 and MEGA 5 for get Heterozygocity value and dendogram genetic distance. The genetic variation analyses showed that heterozygocity value of Bayang was largest (0,56) than Kamang (0,49) and Pitalah duck was smallest (0,44) .The genetic distances analyses showed that Kamang had relatively closer distance with Bayang (0,1393) when compared to Pitalah (0,1649). In the other hand, genetic distances analyses between Bayang and Pitalah was further distance (0,2590). This experiment suggest that Pitalah had more differences characteristics, but Kamang and Bayang had more similarity.
