The ultimate pack goat.......in theory

[Nanno]

So, do goats and ibex have the same number or chromosomes so they can create reproducing offspring? These wouldn't be sterile hybrids would they? Hybrid is kind of a confusing term--I usually think of it as a cross between two separate species that cannot itself reproduce (like mules, zebroids, ligers, and geep) but I know people also use the term when they cross wolves or coyotes with domestic dog breeds. Those, of course, can reproduce and it makes me wonder if wild dogs should even be classified as a different species from domestic.
