Question

the allele for curly hair is incompletely dominant. if a mother is homozygous for curly hair and the father is homozygous for straight hair, what percentage of the offspring will exhibit characteristics of both parents?
○ 25 percent
○ 50 percent
○ 75 percent
○ 100 percent

Explanation:

Step1: Define alleles

Let mother's alleles (curly) be \( CC \), father's (straight) be \( SS \).

Step2: Determine offspring genotype

Incomplete dominance: Offspring get one allele from each parent, so all offspring are \( CS \).

Step3: Analyze phenotype

With incomplete dominance, \( CS \) shows a blend (both curly and straight traits, like wavy hair), so all (100%) offspring exhibit both parents' characteristics.

Answer:

100 percent
