Abstract: In the study,the aim was to investigate the expression of Hairless gene in Inner Mongolia goat.The degenerate primers are designed based on the known conserved sequence of Hairless gene,after the genome DNA was extracted from blood,then the aim gene was amplified by PCR technique,the product of PCR was sequenced.The result indicated that the gene was about 1 985 bp,including 3 exons and 2 introns,and the result of blast also showed it was specific compared with that of cow and sheep in GenBank.
