Comparison for Genetic Diversity between Korean Native Commercial Chicken Brand Groupsusing Microsatellite Markers

摘要

To estimate the genetic characteristics within two brands of Korean native commercial chicken, we used a total of 302 genomic DNAs from two groups (Woorichicken: 152, Hanhyup3chicken: 150). Sizes of 10 microsatellite markers were decided using GeneMapper Software (v.4.0) after analyzing ABI 3130. Genetic diversity indices including expected heterozygosity (Ex H), observed heterozygosity (Ob H) and polymorphism information content (PIC). Frequencies of microsatellites markers were used to estimate heterozygosities and genetic distances. LEI0073 showed the highest value in all genetic diversity (Ex H, Ob H and PIC). On the other hand, MCW322 showed the lowest value in all genetic diversity. The calculated genetic distance of the two brand groups is 0.199 (standard genetic distance) and 0.132 (DA distance). Genetic distances of the two groups were relatively close to each other. Each individual is ramified to two brand groups in phylogenetic dendrogram.
