In human beings the albino trait it recessive and the normal skin colour is dominant. Therefore the probability
of parent’s that are heterozygous for albinism, having an albino child

Answer Details

In humans, the albino trait is recessive, which means that an individual must inherit two copies of the albino gene (one from each parent) to have albinism. Normal skin color is dominant, meaning that an individual only needs one copy of the normal skin color gene to express that trait. If both parents are heterozygous for albinism, meaning they carry one albino gene and one normal skin color gene, then each parent has a 50% chance of passing on the albino gene and a 50% chance of passing on the normal skin color gene to their child. Therefore, the probability of both parents passing on the albino gene to their child is (1/2) x (1/2) = 1/4 or 25%. This means that the probability of the heterozygous parents having an albino child is 1/4 or 25%.
