polymorphisms of caprine gdf9 gene and their association with litter size in jining grey goats. | the exons 1, 2 and flanking region of growth differentiation factor 9 (gdf9) gene in five randomly selected does of jining grey, boer and liaoning cashmere goats were amplified and analyzed. thirteen nucleotide differences were identified in gdf9 gene between sheep (af078545) and goats. four snps (g3288a in intron 1, g423a, a959c [gln320pro] and g1189a [val397ile] in exon 2) were detected in four goat breeds with different prolificacy, in which g3288a was a new snp in goats. the results showed t ... | 2010 | 21181498 |
