The size of the bovine genome is 2.7 Gb (2.7 billion base pairs). [4] It contains approximately 35,092 [4] genes of which 14,000 are common to all mammalian species. Bovines share 80 percent of their genes with humans; cows are less similar to humans than rodents (humans and rodents belong to the clade of Supraprimates) and dogs (humans and dogs belong to the clade of Boreoeutheria).
The Bovine Genome Database is an integrated database for the bovine genome. [1] See also. Bovine genome; References ...
Cattle have some 22,000 genes, of which 80% are shared with humans; they have about 1000 genes that they share with dogs and rodents, but not with humans. Using this bovine "HapMap", researchers can track the differences between breeds that affect meat and milk yields. [ 65 ]
The kouprey was not included in Simpson's taxonomy, [10] while Bohlken (1958) considered the species to be a hybrid between banteng and cattle. [11] Below is the Simpson (1945) taxonomy: [10] Subtribe Bovina (Gray, 1821) Genus Bibos (Hodgson, 1837) Bibos javanicus (d'Alton, 1823) – Banteng; Bibos gaurus (Hamilton-Smith, 1827) – Gaur

The breed's characteristic gene mutation was maintained through linebreeding to the point where the condition was a fixed property in the Belgian Blue breed. [8] In 1978, Belgian Blue cattle were introduced to the United States by Nick Tutt, a farmer from central Canada who emigrated to West Texas and showed the cattle to universities in the ...
The largest extant bovine is the gaur. In many countries, bovid milk and meat is used as food by humans. Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals.
Since horned is recessive to polled, [5] no horned cattle carry the polled allele, but they may also carry scurs. In cattle, genetic expression of the scur gene is different from that of the dominant polled gene, in that the scur gene's expression depends on the sex of the animal. The scur gene is dominant in males and recessive in females. [6]
