the allele for curly hair is incompletely dominant. if a mother is homozygous for curly hair and the father…

Explanation:

Step1: Define alleles

Let $C$ represent the allele for curly - hair and $c$ represent the allele for straight - hair. The mother is homozygous for curly hair ($CC$) and the father is homozygous for straight hair ($cc$).

Step2: Determine gametes

The mother can only produce gametes with the $C$ allele, and the father can only produce gametes with the $c$ allele.

Step3: Use Punnett - square analysis

When we cross $CC$ and $cc$, all of the offspring will have the genotype $Cc$.

Step4: Analyze incomplete dominance

In incomplete dominance, the heterozygous genotype ($Cc$) shows a phenotype that is an intermediate between the two homozygous phenotypes, exhibiting characteristics of both parents. Since all offspring have the genotype $Cc$, 100% of the offspring will exhibit characteristics of both parents.

Answer:

100 percent
