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

Answer

Explanation:

Step1: Define alleles

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

Step2: Determine gametes

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

Step3: Use Punnett - square analysis

When we cross (CC\times cc), all of the offspring will have the genotype (Cc).

Step4: Analyze phenotype

Since the allele for curly hair ((C)) is incompletely dominant over the allele for straight hair ((c)), the heterozygous genotype ((Cc)) will exhibit a phenotype that is a blend of both parents' phenotypes. In this case, the offspring will have characteristics of both parents. The probability of an offspring having characteristics of both parents (heterozygous) is 100%.

Answer:

100 percent
