Since Mark's wife was a carrier, it means that she is heterozygous for the trait. And after Mark got tested, they decided to have children due to no increased risk if they do have children, it means the condition is not an autosomal dominant condition but a recessive condition because if the condition is dominant, only one copy of the affected allele is needed to increase risk.
Thus, with a no increased risk, it means Mark is normal i.e. carries no copy of the recessive allele.
