Incomplete Dominance, Codominance, and Multiple Alleles

The hair form gene shows incomplete dominance. If your genotype is SS, you will have straight hair. If your genotype is CC, you will have curly hair. If your genotype is SC, you will have wavy hair. Mr. and Mrs. Anderson both have wavy hair (SC). What percentage of their children will also have wavy hair (SC)?

• 25%

• 50%

• 75%
