Blood type analysis is used frequently as evidence in paternity suits. Consider the following
hypothetical cases presented in the table. The blood type of the mother and child are given; indicate which
blood type(s) MUST be the father's for each situation.

Answer 1

Answer:

Row 1: Any blood type except AB

Row 2: Blood type A/AB

Row 3: Any blood type except AB

Row 4: Any blood type

Row 5: AB/B

Explanation:

1. If the blood type was AB for the first one (two dominant alleles) then O could not appear as it is recessive.

2. The blood type must contain at least one A allele as AB is obtained from I^A and I^B (already provided by the mother).

3. Once again, the blood type must carry at least one recessive O allele for the O blood type to occur in this child.

4. As long as the blood type either carries a recessive O or another B, the blood type will result in a B.

5. The blood type of the father must contain at least one B for the child to have a B blood type.
