Investigating the Polymorphism of Bone Morphogenetic Protein Receptor-1B (BMPR1B) Gene in Markhoz Goat Breed.

ABSTRACT: Reproductive traits in livestock species are genetically controlled by the action of single genes with a major effect, commonly known as fecundity genes. One of the genes involved in controlling prolificacy is BMPR1B (FecB), a dominant autosomal gene located in chromosome 6 responsible for the fecundity and twinning rate in sheep and goat species. Markhoz goat is a valuable Iranian genetic resource endangered by extinction. Increasing the genetic variability and reproductive performances of Markhoz goat could preserve and enhance its economic value. This study was carried out to detect possible polymorphisms in BMPR1B gene in a sample of 100 Markhoz goats from Iran. DNA samples were screened by PCR-RFLP to assess the presence of the previously reported FecB mutation. Finally, the amplicons from seven goats out of the 100 samples were sequenced. The results showed that all the analyzed individuals did not carry the previously reported FecB mutant allele. However, our findings revealed two novel possible mutations in exon 8 of BMPR1B gene (775A > G and 777G > A) that need further investigations.
