<h3><u>Answer;</u></h3>

<em>Blood group B </em>

<h3><u>Explanation;</u></h3>
  • Mary has blood type A, and the son has blood type AB.
  • An individual with<em><u> blood type A</u></em> must have either one or two copies of A allele, that is<em><u> either AA, or AO genotype.</u></em>
  • Similarly with<em><u> blood group B</u></em>, the genotype may be either be<em><u> BB or BO. </u></em>
  • Therefore, since <em><u>Mary has blood group A, and the son Bill has blood group AB, </u></em>it means that the father would have blood group B. This is because Mary will pass A allele to their son and the father will pass B allele to the son.
