MILWAUKEE - Two jaguar cubs are bringing more than just cooing visitors to Milwaukee's zoo. They're introducing new genes to the endangered species' captive population.
The spotted brothers were born Nov. 13. They don't have official names yet, but zoo keepers are calling them "Dots" and "Gaps," because of markings on their heads.
Their father was born in the wild, which is rare.
Stacey Johnson, coordinator of the jaguar species survival plan for the American Zoo and Aquarium Association, said the father's new genes will help sustain the zoo population over next 100 years.
It also helps that both cubs are male. Johnson said zoos currently have more female jaguars than male.
The cubs are still too small for their exhibit. But zoo keepers said they should be ready by early February.
