| [origin and genetic diversity of mongolian and chinese sheep using mitochondrial dna d-loop sequences]. | to determine the origin and gene diversity of the chinese and mongolian domestic sheep, a partial fragment of mitochondrial dna d-loop was sequenced for total number of 314 individuals from nine chinese sheep populations and 11 mongolian sheep populations. the results show no difference in nucleotide composition between chinese and mongolian sheep mtdna d-loop sequences. however, more variables were identified in mongolian sheep (26.85% of the sites) than that in chinese sheep (24.22%). in china ... | 2005 | 16459654 |
