Research Of Mating System In Tupaia Belangeri By Microsatellite Dna Markers

Mating system of a population refers to the general behavioral strategies which employed in obtaining mates. In order to investigate the genetic parentage of 151 individuals in Tupaia belangeri from Haikou Forest Farm, 8 microsatellite loci with higher polymorphic characters were used for genetic relationship analysis. The results showed that the number of alleles per polymorphic locus in 151 individuals ranged from 2 to 9. The average observed and expected heterozygosities per locus ranged from 0.2476 to 0.8367 and from 0.2789 to 0.7773, respectively. While the polymorphic information content ranged from 0.2469 to 0.7773. Except the locus (TBC1) deviated from Hardy-Weinberg equilibrium, the others 7 microsatellite loci were employed to research the mating system in T. belangeri, which found that non-strictly monogamous in T. belangeri, but exhibited evidence of multiple paternity. All of the results suggested that characteristics of 8 microsatellite loci provide an excellent tool for the research of mating systems and fine-scaled population structuring of tree shrew, which was the first molecular evidence for mating system in T. belangeri.
