Allele frequencies, numbers of alleles and observed heterozygosities (HO) for the Aime-MHC class II alpha genes.

Numbers in parentheses are the total numbers of alleles.

*: P<0.05 and **: P<0.01.

a

Alleles represented in bold were newly identified in current study, while the others were defined in a previous study [30];

b

and c indicate the allele was LSH-specific and QLI-specific (Qinling subspecies-specific), respectively.
