A dzo (also spelled zo, zho and dzho,
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 khainag crossed with either a domestic bull or yak bull is called ortoom (ортоом, three-quarter-bred) and an ortoom crossed with a domestic bull or yak bull results in a usan güzee (усан гүзээ, one-eighth-bred).[6][7]
Dzos inherit two distinct protein types, one from each parent, leading to alterations in their mitochondrial structure and function.[8] Consequently, this adaptation significantly enhances the dzo's capacity to thrive at higher altitudes compared to either parent.
