Suppose two men could be the father of a child. Before doing an expensive paternity test, the geneticist involved in the case decides to ask about the blood-type of all individuals. However, Man 2. refuses to provide a blood sample. Given the following blood-types, could you still determine the paternity of the child and why? [4 pt] Mother: A-type Man 1: АB-type Child: O-type Man 2: (unknown)

I’m having trouble answering this question can you please help?
Suppose two men could be the father of a child. Before doing an expensive paternity test, the geneticist involved in the case decides to ask about the
blood-type of all individuals. However, Man 2. refuses to provide a blood sample. Given the following blood-types, could you still determine the paternity of
the child and why? [4 pt]
Mother:
A-type
Man 1:
АB-ype
Child:
O-type
Man 2:
(unknown)
No. Since O is dominant to A and B, the mother's contribution of an O allele could determine the child's O phenotype, regardless of the father.
No. Since O is recessive to A and B, the child could have received an O from Man 1 or Man 2, in order to generate an O phenotype in the child.
Yes. The only way for the child to be O-type would be if he received an O allele from Man 2 and an O allele from the Mother.
Yes. The only way for the child to be O-type would be if he received an O allele from Man 1, which was likely being masked by the other dominant
alleles.
