Association between Microsatellite Polymorphism and Body Size Traits in Sonid Bactrian Camels

In this study, 17 microsatellite markers were used to analyze the genetic diversity of Sonid bactrian camels, and the correlation between microsatellite markers and their body size was analyzed to find microsatellite markers associated with the body size traits of Sonid bactrian camels, so as to provide reference for marker-assisted selection of Sonid bactrian camels. The results showed that 64 alleles were detected in 17 microsatellite markers. The average number of alleles was 3.7647, the average heterozygosity was 0.6205, and the average polymorphism information content was 0.5602. It showed that the population of Sonid bactrian camel had high genetic diversity. Among 17 microsatellite markers, 4 microsatellites were found to be associated with body size traits of Sonid bactrian camels. The body length of AB genotype labeled LCA33 was significantly higher than that of AA genotype (P
