This study investigated the molecular genetic variation of BMP15 gene of some selected mammalian species with a view to providing relevant genetic information for breeding and selection programmes in the studied species using computational methods. A total of thirty seven (37) BMP15 nucleotide sequences comprising goats (18), sheep (6), cattle (6), swine (4) and chicken (3) were retrieved from the GenBank. Sequence alignment, translation and comparison of the BMP15 gene of the various species were done with ClustalW. High degree of polymorphism of BMP15 gene was observed among the studied species. The significant value (P bovidae family (goat, sheep and cattle). The present information could guide future efforts involving selection of markers of fecundity to improve genetically livestock species in Nigeria.展开更多
