Dzomo can be [[backcrossing|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).<ref name="son"/><ref>[http://ci.nii.ac.jp/naid/110004313817/en Takase Hisabumi, Kh.

The spelling ZO is a particularly important word in [[Scrabble]] as it is an easy way to use a Z tile, and can create a very high score, particularly when placed on a triple letter or word score when forming vertical and horizontal words simultaneously. ZO can subsequently be extended to DZO, ZOS, or other words such as ZOA. |

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. Alternative Romanizations of the Tibetan names include dzho, zho and zo. 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]

The spelling ZO is a particularly important word in Scrabble as it is an easy way to use a Z tile, and can create a very high score, particularly when placed on a triple letter or word score when forming vertical and horizontal words simultaneously. ZO can subsequently be extended to DZO, ZOS, or other words such as ZOA.
