Our study used MHC class IIb gene exon3 complete sequence as markers to investigate genetic variability, selection and population differentiation in Chinese alligator. In this study, 282 bp MHC IIb exon3 complete sequence was got, none of the sequences contained insertions/deletions or stop codons, suggesting that all sequences might come from functional molecules in the genome. The neighbor-joining (NJ) tree revealed that Xuangzhou and Changxing populations were genetically close related, while Wild population showed the most diverse from the other. Gene flow (Nm) was very higher than one, suggesting that inter-group gene flow may have occurred. Furthermore, the results showed that MHC IIb gene might be a good molecular marker, we think that this technology could be used for Chinese alligator breeding and releasing in future.
