When they mate a yak and cow produce what?

When a yak and a cow mate, they produce a hybrid offspring called a zo hybrid.

Here's why:

* Yak: A type of bovine native to the high plateaus of Central Asia.

* Cow: A domesticated bovine species (specifically, a female).

* Hybrid: An offspring resulting from the breeding of two different species or varieties.

Zo hybrids are typically fertile and can inherit traits from both parents, such as the yak's hardiness and the cow's milk production.
