Often albinism can be a fatal gene. In groups of animals where one would only see female albinos probably means it is a fatal gene in males.

If I remember correctly if both parents in certain species are albino the young do not survive. I think this occurs in horses. Albinism is a recessive gene.

The photos below may be an albino zebra foal from Kenya. It's hard to see if the eyes are pink on it.

Albinos aren't necessarily all white either. Albinism is just the lack of black pigment cells. I've seen some reddish colored blue wildebeest that were probably albinos. They look reddish, probably closer to pink, due to the lack of black pigment. These were captive and part of some farmer's breeding program.

Some reptile breeders go wild with this stuff and you'll see some pretty odd colored frogs and pythons, yellow ones, white ones, etc. But they have no pigment in their eye (they are pink) and are thus albinos.
