Husky and polar bear mix

What happens when you cross a polar bear with a grizzly bear? Turns out, the babies sport a mix of features, such as partially hollow hairs. This mating story began in when a female brown bear gave birth to two brown-polar bear hybrids at the Osnabruck Zoo in Germany. The cubs were transported to another zoo to see what would happen if they were raised without the intervening of either their polar-bear or grizzly-bear parents. When scientists examined the offspring, they found the bears had long necks and visible tails similar to polar bears and small shoulder humps like brown bears. Some features showed a mix between the parents: For instance, the soles of the hybrids' feet were partly covered in hair. Polar bears have hair-covered feet while grizzlies have hairless soles. And the hair on the hybrids' back was hollow, but with smaller hollow regions than in hair of polar bears. The male hybrid, however, turned out to be sterile.

A grizzly—polar bear hybrid also named grolar bear , pizzly bear , zebra bear , [1] [2] grizzlar , or nanulak is a rare ursid hybrid that has occurred both in captivity and in the wild. In , the occurrence of this hybrid in nature was confirmed by testing the DNA of a unique-looking bear who had been shot near Sachs Harbour , Northwest Territories , on Banks Island in the Canadian Arctic. The number of confirmed hybrids has since risen to eight, all of them descending from the same female polar bear. Possible wild-bred polar bear — grizzly bear hybrids have been reported and shot in the past, but DNA tests were not available to verify the bears' ancestry. Genetic analysis has revealed multiple instances of introgressive hybridization between bear species, [4] [5] [6] including introgression of polar bear DNA into brown bears during the Pleistocene "grizzly bear" is a local common name for Ursus arctos whereas "brown bear" is used internationally and in science to refer to the species as a whole. With several suspected sightings and eight confirmed cases, [3] theories of how such hybrids might naturally occur have become more than hypothetical. Although these sister species often occupy adjacent regions, direct contact has not been the norm because polar bears hunt, breed, and sometimes even make maternity dens on sea ice, where brown bears have an overwhelmingly terrestrial lifestyle. Scientists have been unable to give an exact explanation for the phenomenon. One theory suggests that as the grizzly population increases, male bears leave their dens sooner while females stay with their cubs. This means that to the male grizzlies, female polar bears have become viable mates.
