摘要： Although it has been investigated for many years, the physiological processes regulating prolificacy in sheep remains unclear because of regulation by many genes. To better understand the effects of three single nucleotide polymorphisms (SNPs) comprising g.48462350C > T in BMP2, g.58171856C > G and g.58171886A > C in BMP7, a population genetic analysis was conducted using data obtained from genotyping in 768 sheep from six breeds (three polytocous and three monotocous). The results indicate that all the sheep breeds were considered to conform to the Hardy-Weinberg equilibrium (P > 0.05). The associations of these three SNPs with litter size in 384 Small Tail Han sheep were analyzed, therefore, and found to be correlated with fecundity as assessed by mean litter size (P < 0.05). Bioinformatic analysis indicated there was a transmembrane domain change that occurred after a mutation in BMP2 at g.48462350C > T, and changes involving transcription factors such as USF1, USF2 and INMS1 in the BMP7 promoter region might be involved in greater sheep prolificacy.
