Every year, some of these individuals ended up mating outside their species, producing a small number of hybrids. , a bear shot in Nunavut, Canada was thought to be a hybrid based on its cream-colored coat, but genetic testing later determined that it was, However, true hybrids have definitely turned up in the wild in recent years.
