Polymorphism was detected for exon 3 of BMP4 gene in four sheep breeds. For exon 3, three genotypes were detected in four sheep breeds. In Small Tail Han, Chinese Merino, Corriedale and South African Mutton Merino sheep, frequency of genotype AA was 0.017, 0.216, 0.115, 0.429, frequency of genotype AB was 0.102, 0.317, 0.269, 0.500, frequency of genotype BB was 0.881, 0.467, 0.616, 0.071, respectively. Sequencing revealed one singlenucleotide mutation C→A at 305 bp of exon 3 of BMP4 gene in genotype BB in comparison to genotype AA, and this mutation resulted in an amino acid change of alanine→aspartic acid.

In Small Tail Han sheep, Chinese Merino sheep, Corriedale sheep and South African Mutton Merino sheep, frequency of AA genotype was 0.58, 0.98, 0.96, 1.00, frequency of AB genotype was 0.40, 0.02, 0.04, 0.00, frequency of BB genotype was 0.02, 0.00, 0.00, 0.00, respectively. The ewes with mutation homozygous genotype BB or mutation heterozygous genotype AB had 1.45 at 305 bp of exon 3 of BMP4 gene in the BB genotype in comparison to the AA genotype, and this mutation resulted in an amino acid change: alanine—?aspartic acid. The ewes with genotype BB had 0.61 P
