瘤牛

根据形态特征和细胞遗传学的研究，大额牛是Bos属中独立的一个种（Bosfrontalis），很可能起源于雄性野牛和雌性瘤牛的杂交后裔。

支持瘤牛（B.indicus）为独立驯化、起源于印度次大陆的假说。

Furthermore our results also confirm the hypothesis that B. indicus has undergone a separate domestication event and originated from the Indian subcontinent .

普通牛、瘤牛、牦牛、大额牛序列间没有显示出完全的分化，它们也没有共同拥有相同的核苷酸序列。

No complete differentiation appeared among Bos taurus , Bos indicus , Bos grunniens , Bos frontalis and no shared nucleotide sequence among them .
