Hair color, eye color and widows peak are all Mendelain dominant recessive traits. When a couple who is heterozygous (both of them mind you) for each of the three traits what are the odds that they will encompass a child which has dark hair (Dom), Blue Eyes (Rec) and a widows peak (Dom). I think the answer must be a fraction with the denominator being over 50

Is it possible a child was switched at birth if the child's blood type is not Couple 1's theirs; they think a switch must have occurred? Couple 1 (the plaintiffs) have AB+ and 0+ blood, and their son has 0+ blood. Couple 2 (the other couple from the hospital) have B+ and A+ blood. Their child has B+ blood. Is couple number one right on their supposition and describe why? They are all parents and there is no milkman or postman included. My thought is no it is not correct that the child of couple one belongs to couple one however why if that is even accurate.
