Chinese native sheep populations, Hu sheep, Tong sheep,
Small-tailed Han sheep and Tan sheep were used to study the
efficiency of genetic markers. The genetic markers used in
this study include morphological and ecological indices,
blood protein enzyme, microsatellite DNA and the combination
of three markers. The results showed that the morphological
and ecological indices are not accurate tools to determine
the relationships among populations. In contrast, blood
protein enzyme and microsatellite DNA were the best markers
for genetic diversity among sheep populations. Therefore,
selection of markers depends on the aim of research; for
instance neutral markers are selected to study the origin of
breeds, trait indices for economical or ecological
classification, and multi-combined genetic markers for the
relations among populations.
Key words:
Genetic markers, genetic differentiation, genetic detection
efficiency. |
