Microsatellite DNA Typing for Assessment of Genetic Variability in Guangxi Three-yellow Chickens

摘要

In the present study, researchers report a genetic diversity study of Guangxi Three-yellow chicken by use of 30 microsatellite markers. Guangxi Three-yellow chicken is a light-body type breed with good meat quality which is famous for its three yellow morphology features in China. Microsatellite genotypes were derived and allelic and genotypic frequencied, hererozygosities and gene diversity were estimated. A total of 212 alleles were distinguished. All the microsatellites were polymorphic with mean allelic number of 7.067 ranging 2-11 per locus. The expected hererozygosity in the population ranged between 0.500 and 0.847 with mean of 0.734 indicating considerable genetic variation in this population. The FIS values indicated low levels of inbreeding in the population. Genetic bottleneck hypotheses were also explored. The data suggest that the Guangxi Three-yellow chicken population has not experienced a genetic bottleneck in the recent past.
