OMAHA, Neb. (AP) — Omaha zoo officials say one of its lionesses has given birth to a rare white cub.

The Henry Doorly Zoo and Aquarium says the male cub is one of three born late last week, two boys and one girl. Zoo officials say lion cubs typically weigh about three pounds at birth and that their cubs weigh just over four pounds.

They say the cubs will soon go on display with their mother and will likely open their eyes within a week or two.

Zoo officials say the inheritance of the white coloring is not fully understood and may be linked to a rare recessive gene from each parent.
