我们重建的表型巴尔托,英雄雪橇犬运输白喉抗毒素,阿拉斯加诺姆于1925年,使用进化约束估计从Zoonomia对齐的240种哺乳动物和682个基因组的狗和狼的21世纪。巴尔托只是分享他的一部分不同的祖先与epperian西伯利亚哈士奇品种。巴尔托的基因型预测了现代雪橇犬品种的非典型皮毛特征和略小的身材。与格陵兰雪橇犬相比,他的淀粉消化能力更强,并且在与骨骼和皮肤发育相关的基因的限制位置上获得了一系列衍生的纯合编码变体。我们建议,巴尔托的人口的起源,这是近亲繁殖和遗传健康比现代品种,适应了20世纪20年代阿拉斯加的极端环境。比较基因组学揭示了1925年血清运行的著名雪橇犬Balto与现代狗之间的基因型-表型联系。
We reconstruct the phenotype of Balto, the heroic sled dog renowned for transporting diphtheria antitoxin to Nome, Alaska in 1925, using evolutionary constraint estimates from the Zoonomia alignment of 240 mammals and 682 genomes from dogs and wolves of the 21st century. Balto shares just part of his diverse ancestry with the eponymous Siberian husky breed. Balto’s genotype predicts a combination of coat features atypical for modern sled dog breeds, and a slightly smaller stature. He had enhanced starch digestion compared with Greenland sled dogs and a compendium of derived homozygous coding variants at constrained positions in genes connected to bone and skin development. We propose that Balto’s population of origin, which was less inbred and genetically healthier than modern breeds, was adapted to the extreme environment of 1920s Alaska. Comparative genomics uncovers genotype-phenotype links between Balto, famed sled dog of the 1925 Serum Run, and modern dogs.
