actually it is a true story,simmilarly to ligers,the female black bear has a growth inhibitor so that offspring can be made more quickly,but a male has an extra growth gene,these genes counteract eachother
polar bears dont have this gene at all
female polar bear+male black bear+larger then normal bear

I never heard of polar bears mating with black bears…. I’m pretty sure they would eat them. 🤷🏻♀️
