Since albinism is a recessive character, a child will be albino only if it is homozygous for albinism genes. Since parents have normal skin, it means they are heterozygous. As a result of cross between two heterozygous parents, 25% of the children will be homozygous recessive. The nature of the second child is not affected in any way by the nature of the first child because both are independent events.
