I have a female blacktail that was captive bred. She's now a yearling and she still seems pretty uniform in color - her tail is no darker than the rest of her. I had a male that was a clutchmate of hers, and he was pretty normal blacktail looking.
Is this normal? Or is it within their natural color morphology? Or is it possible her lineage includes genes from other subs (I'm not sure what subs, other than unicolor, their range overlaps with)?
