"Aman and a woman are going to have a baby and they want to know the probability that their child will have a certain type of deafness, an autosomal recessive genetic condition. The woman has normal hearing; but has been tested and knows that she is a carrier at this gene locus: Her husband is homozygous recessive at this gene locus and is deaf. What is the probability that the couple's child will be deaf? (Hint: It will be helpful to draw a Punnett square to arrive at your answer:) Select one: 0% b. 25% C. 50% d. 75% e. 100%"

Step 1
The woman is a carrier, which means she has one normal allele and one recessive allele for the deafness gene. We can represent her genotype as Nn, where N is the normal allele and n is the recessive allele. The husband is homozygous recessive, which means he has Show more…

If the dominant allele $A$ is necessary for hearing in humans, and another allele, $B$, located on a different chromosome, results in deafness no matter what other genes are present, what percentage of the offspring of the marriage of $a a B b \times A a b b$ will be deaf?

A man and woman are each heterozygous for both biotinidase deficiency (B/b) and deafness (D/d). Both conditions are autosomal recessive and assort independently. They plan to marry and start a family. What proportion of the children of this couple will have neither condition phenotypically?
