A grizzly bear cub born in the Yellowstone area carries genetic material from outside the region's isolated population. The birth is the first recorded instance of such mixing for that group. Wildlife observers documented the cub this spring. Genetic testing confirmed the presence of DNA from bears beyond the Yellowstone ecosystem.
Genetic milestone The new genetic input could reduce inbreeding risks that have affected the local bears. Officials have monitored the population for decades under federal recovery programs. Conservation groups described the event as progress toward long-term viability.
They noted that outside DNA may help the bears adapt to changing conditions. Further monitoring will track the cub's survival and any additional births with similar genetic profiles.
