A dzo (Tibetan མཛོ་ mdzo) (also spelled zo, zho and dzho) 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 dzomo or zhom. In Mongolian it is called khainag (хайнаг). There is also the English language portmanteau term of yakow; a combination of the words yak and cow, though this is rarely used.
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.[1] In Mongolia and Tibet, khainags are thought to be more productive than cattle or yaks in terms of both milk and meat production.[2][3]
Dzomo can be back crossed. As a result, many supposedly pure yak or pure cattle probably carry each other's genetic material. In Mongolia and Tibet, the result of a khainag crossed with either a domestic bull or yak bull is called ortoom (three-quarter-bred) and an ortoom crossed with a domestic bull or yak bull results in a usan güzee (one-eighth-bred).[3][4]
Scrabble
The spelling ZO is particularly important in Scrabble as it is an easy way to use a Z tile, and can create a high score when placed on a triple letter or word score, especially when forming vertical and horizontal words simultaneously which results in a score of more than 60. ZO can subsequently be extended to DZO, ZOS, or other words such as ZOA.
