Question 5

A couple approaches a genetic counselor concerned about the risk of their future child inheriting a rare autosomal recessive disorder. The father's genetic testing reveals he is a carrier (heterozygous) for the disorder, while the mother's test shows she is not a carrier (homozygous dominant). Based on Mendelian inheritance principles, what is the probability that their child will be a carrier for this specific recessive disorder?

Accepted Answer

C. 50% — The father has a genotype of Aa (carrier) and the mother has AA (non-carrier). A Punnett square analysis shows that 50% of their offspring will inherit an 'A' allele from the mother and an 'a' allele from the father, resulting in a heterozygous (Aa) genotype, making them carriers. The other 50% will be AA (non-carriers), and there is no chance for the child to inherit the disorder (aa) as the mother does not carry the recessive allele.
