Yeah that makes more sense. I assume if they had the kit for widespread DNA tests, they could see who has what subspeciesI think it would make no sense to be the only facility in North America to have maneless zebra. It is far more cost effective if the AZA would establish a pure-bred Grant's or other steppe zebra SSP .... (ATM, from what I know they do a mix/hit and miss with them).
That being said, I assume the AZA's current modus operandi is to just do away with plains zebras altogether in favor of their more endangered cousins
