Answer 2

criss cross inheritance- where the mother is carrier for color blind gene, out of her two x chromosomes if one x chromosome is carrying defective gene there is probability of her son being color blind is 50% as she can give either of her x chromosomes to her son. if she has got defective gene containing x chromosomes both from her father and mother then her son is 100% color blind. women have two x chromosomes so if one x chromosome has defective gene then it can be masked by the other x chromosome. men get only one x chromosome from their mother so they become colour blind if their mother gives them x chromosome with defective gene. father only gives y chromosome to son, the color blind gene is x chromosome linked. so it is called sex linked inheritance (x-linked)
