Answer:
75%
Explanation:
The autosomal gene for baldness has two possible alleles: Hb (baldness) and Hn (nonbaldness).
A man and a woman, both heterozygous <em>HnHb,</em> have a son. Each parent produces gametes <em>Hn</em> or <em>Hb</em>.
The possible genotypes of their children, resulting from the combinations of those gametes, are:
In males, the Hb allele is dominant. Therefore, their son has a chance of 3/4 = 0.75 = 75% of having the Hb allele which determines baldness.
