The mutation in the MC1R gene also occurs in brunets, although it's less common.

黑素皮质素受体基因变异也可能在深色头发的人群中发生，但几率较小。

The MC1R gene is related to coat color in cattle and to lactoprotein content in milk.

牛mc1r基因不仅与毛色有关，而且与牛乳中乳蛋白的含量有关。

These proteins have a phenylalanine in a key position that plays an essential role in binding on MC1R receptors.

这种蛋白质中在关键位置上含有苯基丙氨酸，它在与MC1R受体结合时起到很重要的作用。

But, by coincidence, he then discovered a group of scientists working on a mouse called Peromyscus that possesses the same less active variation of the MC1R gene as mammoths did.
