Bone morphogenetic protein 15 (BMP15) is crucial factor for ovulation as well as for increasing litter size. In the present investigation efforts had been carried out to assess the genetic variations in Exon 2 region of BMP15 in goat, using polymerase chain reaction single strand conformation polymorphism (PCR-SSCP) sequencing methods and cooperated frequency distribution to discuss its possibility of related fecundity. Across the 144samples from six breeds were identified in the A963G location of BMP15 using PCR-SSCP and sequences technology. A963A genotype was the most frequent (85.4%) and G963G was the least frequent with a frequency of 4.2% and A963G is 10.4%. It revealed non significant different between high and low fecundity breed. Therefore, this single nucleotide variant is not common Bio-Marker for fecundity in Goat.

The objective of the present study was to explore a predictor of superovulation response on the basis of associations between the number of embryos recovered and gene polymorphism. Variation in the goat LHβ and GnRHR genes was investigated using polymerase chain reaction–single-strand conformational polymorphism and DNA sequencing. Two single nucleotide polymorphisms (SNPs) were identified in the 5′-UTR of LHβ gene (A59C, P1 locus) and in the Exon 2 of GnRHR gene (T177A, P6 locus). At the P1 locus in both breeds, the frequencies of one allele were 0.46 and 0.51, respectively. At the P6 locus, the minor allele frequency was 0.23. Associations of both SNPs with the number of embryos recovered and the corpus luteum number were evaluated in Boer and Shaanbei goat breeds. Association analysis showed that both SNPs had significant (P < 0.05) effects on the number of embryos recovered and corpus luteum number. These results indicate that LHβ and GnRHR genes are potential markers for the number of embryos recovered.
