DRB3.2 gene polymorphism and its association with pashmina production in Changthangi goat.
PstI and TaqI restriction fragment length polymorphism (RFLP) of caprine DRB3.2 revealed three genotypes under each RFLP in Changthangi goat. The genotypic and allelic frequency in PstI RFLP was calculated as 0.07, 0.72 and 0.20 for PP, Pp and pp genotypes and 0.43 and 0.57 for P and p alleles. In TaqI RFLP the frequencies were observed as 0.11, 0.61 and 0.27 for TT, Tt and tt genotypes and 0.41, 0.59 for T and t alleles. Alignment study indicates variability of nucleotides and amino acids between alleles and different breeds of goats. The nucleotide sequences reported in this paper have been submitted to the European Molecular Biology Laboratory GenBank and the accession numbers were AY496935, AY496061 and AY496062. A significant affect (P <or= 0.05) of MHC DRB3.2 PstI polymorphism was found on the first and second year of pashmina production.
