A dzo (also spelled zo, zho and dzho, Шаблон:Lang-bo) is a hybrid between the yak and domestic cattle. The word dzo technically refers to a male hybrid, while a female is known as a Шаблон:Transliteration or Шаблон:Transliteration. In Mongolian, it is called a Шаблон:Transliteration (хайнаг). There is also the English language portmanteau term of yattle, a combination of the words yak and cattle,[1] as well as yakow,[2][3] a combination of the words yak and cow.

Dzomo are fertile (or, fecund) while dzo are sterile. As they are a product of the hybrid genetic phenomenon of heterosis (hybrid vigor), they are larger and stronger than yak or cattle from the region.[4] In Mongolia and Tibet, khainags are thought to be more productive than cattle or yaks in terms of both milk and meat production.[5][6]

Dzomo can be back crossed. As a result, many supposedly pure yak or pure cattle probably carry each other's genetic material. In Mongolia, the result of a Шаблон:Transliteration crossed with either a domestic bull or yak bull is called Шаблон:Transliteration (ортоом, three-quarter-bred) and an Шаблон:Transliteration crossed with a domestic bull or yak bull results in a Шаблон:Transliteration (усан гүзээ, one-eighth-bred).[6][7]

Dzo inherit two different types of proteins, one from each parent, and their mitochondrial structure and function changes.[8] This significantly changes the dzo's ability to survive in higher altitudes than both parents can.
