A woman with type A blood has a child with type A blood. Which of the following men could NOT be the father

B. All males could be the father

Explanation:

A woman with type A blood either has the genotype AA or Ai. A child with type A blood will also either have AA or Ai.

Type B blood is BB or Bi. Type AB blood is AB. Type O is ii.

To find out the men not be the father, you have to do Punnett squares between the mother and father.

AA mother with BB father - type AB child

AA mother with Bi father - type AB and type A child

Ai mother with BB father - type AB and type B child

Ai mother with Bi father - type AB, type B, type A, and type O child

AA mother with AA father - type A child

AA mother with Ai father - type A child

Ai mother with AA father - type A child

Ai mother with Ai father - type A and type O child

AA mother with AB father - type AB and type A child

Ai mother with AB father - type AB, type A, and type B child

According to these crosses, all males could be the father. The father with type B blood must have the genotype Bi. The father with type A blood can have either genotype AA or Ai. The father with type AB blood will always produce a type A child except with a woman who has the genotype BB for type B blood.

Hope that helps.
