【摘要】 绵羊繁殖性能受到强烈的选择压力。基因突变会导致排卵率发生变化,为繁殖性能提供了一种契机。到目前为止,已经识别出BMP15、GDF9和BMPR1B3个基因突变,会导致绵羊排卵率变化。笔者介绍了已识别的单基因突变对排卵率的影响,以及这些发现对卵巢功能控制提供新的见解。更多还原

【Abstract】 Sheep populations have been subjected to strong selection pressure to improve reproductive success. Genetic mutations caused ovulation rate change provide an opportunity. To date,three genes,which are BMP15、GDF9 and BMPR1 B gene,have been identified as having mutations that lead to alterations in ovulation in sheep. This review is focused on the identification of the mutations affecting ovulation rate and how these discoveries have provided new insights into control of ovarian function.更多还原
