Abstract: | Genetic diversities based on the mtDNA control region were measured for both a wild population (n = 26) and a captive population (n = 18) of the black muntjac. In total, nine haplotypes were obtained from 44 samples. The wild population exhibited a low
nucleotide diversity (π = 0.00562), which suggests that the black muntjac had a small effective population size historically.
In contrast to its low nucleotide diversity, haplotype diversity (h = 0.862) of the wild population was relatively high. Haplotype distribution among local samples shows a distinct difference.
As anticipated because of the paucity of available founders, nucleotide diversity (π = 0.00214) of the captive population
was very low. Additionally, a high degree of haplotype identity and an obvious haplotype frequency bias was revealed in the
captive population, which implies that the current breeding program should be readjusted to balance distributions of haplotypes,
and some new founders should be introduced to the captive population to alleviate potential inbreeding depression. |
