摘要： Genetic coadaptability of wild Japanese quail, wild Common quail and Domestic quail populations in China was studied using 7 microsatellite DNA markers and Monte Carlo method to test genetic disequilibrium. The molecular effects of genetic coadaptability were analyzed through a new statistical model of neutral site. The results showed that genetic coadaptability dominated the genetic disequilibrium of the three quail populations, and totally 16.67%, 9.66% and 10.05% of non-allelic combinations were in the genetic disequilibrium in wild Japanese quail, wild Common quail and Domestic quail populations, respectively. Genetic coadaptability existed at almost all the tested sites. In the molecular point of view, genetic coadaptability plays an important role of keeping lots of polymorphisms in natural populations. Therefore, it is another key factor to the genetic disequilibrium in the population except for linkage. The results enrich the conceptions and connotations of genetic disequilibrium, and help us know more about genetic coadaptability and its effects, and lay a foundation of evaluation and protection of wild quail genetic resources in China.
