Changes in the Population Genetic Structure of Captive Forest Musk Deer <i>(Moschus berezovskii)</i> with the Increasing Number of Generation under Closed Breeding Conditions

Changes in the Population Genetic Structure of Captive Forest Musk Deer <i>(Moschus berezovskii)</i> with the Increasing Number of Generation under Closed Breeding Conditions

We investigated the genetic diversity of the population of captive forest musk deer (<i>Moschus berezovskii</i>) in <i>Barkam</i> Musk Deer Breeding Centre using twelve microsatellite markers, and then analyzed the change in genetic structure of successive generation groups f...

The result suggested that the captive population was facing the pressure of inbreeding (F<sub>IS</sub> = 0.115) and the subsequent loss of genetic diversity. Therefore, it is necessary to improve the breeding management system of the captive population by preventing close relatives from mating or inducing new individuals from the exotic population.https://www.mdpi.com/2076-2615/10/2/255forest musk deermicrosatellite dnagenetic diversitypopulation genetic structure
