Alice has type A blood and her husband Mark has Type B blood
TiliK225 [7]

Answer:

From this information, we know both parents are heterozygous. This means each parent has an O allele to produce a child with type O blood. A and B blood type alleles are dominant to the O allele which allows one to be heterozygous and express A and B blood type but still have an O allele. This makes that Alice's blood type would be AO. Additionally, the father genotype would have to be BO.
