Abstract
Twelve Chinese indigenous goat populations were genotyped for
twenty-six microsatellite markers recommended by the EU Sheep and Goat
Biodiversity Project. A total of 452 goats were tested. Seventeen of
the 26 microsatellite markers used in this analysis had four or more
alleles. The mean expected heterozygosity and the mean observed
heterozygosity for the population varied from 0.611 to 0.784 and 0.602
to 0.783 respectively. The mean
(0.105) demonstrated that
about 89.5% of the total genetic variation was due to the genetic
differentiation within each population. A phylogenetic tree based on
the Nei (1978) standard genetic distance displayed a remarkable degree
of consistency with their different geographical origins and their
presumed migration throughout China. The correspondence analysis did
not only distinguish population groups, but also confirmed the above
results, classifying the important populations contributing to
diversity. Additionally, some specific alleles were shown to be
important in the construction of the population structure. The study
analyzed the recent origins of these populations and contributed to
the knowledge and genetic characterization of Chinese indigenous goat
populations. In addition, the seventeen microsatellites recommended by
the EU Sheep and Goat Biodiversity Project proved to be useful for the
biodiversity studies in goat breeds.
