An individual with (naturally) curly hair and an individual with (naturally) straight hair mate; all of their offspring have (naturally) wavy hair. if an individual with wavy hair mates with an individual with straight hair, what is the probability that their child will have curly hair?
a. 75%
b. 100%
c. 25%
d. 0%
e, 50%

d - 0%

Explanation:

Let curly hair gene be represented by AA

Straight hair gene will be aa

Since a cross between curly and straight hair resulted in wavy hair, it means wavy hair is an heterozygous condition Aa

Crossing wavy hair Aa with straight hair aa.

Offspring's genotype will be: Aa, Aa, aa, aa

Phenotypically, Aa is wavy hair and aa is straight hair, it means none of the offspring will have curly hair (0% probability).

The correct option is d.

the answer would be   10%
