摘要: One of the most important traits for both animal science and livestock production is number offspring a species. This study was performed to identify differentially evolved genes their distinct functions that influence at birth by comparative analysis eight monotocous mammals seven polytocous in scopes: specific amino acid substitution with site-wise adaptive evolution, gene expansion orthologous group. The mutually exclusive among 16 mammalian species identified five candidate genes. These were directly indirectly related ovulation. Furthermore, mammals, EPH family found have undergone expansion. Previously, EPHA4 positively affect litter size pigs supports possibility playing role determining per birth. this offer basis from which differences between can be studied. these may harbor some clues underlying mechanism, determines prove useful breeding strategies.
