Rare white giraffes caught on video (video)

Two white giraffes, an adult and a calf, were captured on camera in Garissa County, Kenya, by a conservation group.
The ghostly white giraffes seem otherworldly with their lack of colouring and markings.
Their appearance is a result of a genetic condition called leucism in which there is a partial loss of pigmentation.

Black family has white children! (video)

When Rosamere Fernanda de Andrade first held her newborn baby she assumed there had been a mix up.  Rosamere and ex-husband, Joao, are both black – but their daughter, Ruth, had white skin, blonde hair and blue eyes. But it was no mistake – Ruth, suffers from a rare generic condition called albinism and has no skin pigment.
