It is not impossible to have twins like that.... If you guys notice, the parents are both heterogenous, in other words, they are mixed of black and white...
One of the children got both white genes from her parents. The mother's genotype is BW and the father is BW also. Each one of them give one of their genes to their offsprings. The white child got W's from each parent and the other child got both B's from parents. Therfore the genotype of the white child is WW and the genotype of the black child is BB.
