Sagot :
Answer: e. 100% dimpled cheeks
Explanation: The allele for dimpled cheeks (D) is dominant, meaning that it only needs one copy for the phenotype to be expressed. On the other hand, the allele for smooth cheeks (d) is recessive, meaning that humans need two copies of the allele in order for the trait to be expressed. Therefore, an individual with genotype "Dd" will have dimpled cheeks since they have a dominant allele for dimpled cheeks.
By using a Punnett Square, we can determine that all of the offspring will have the genotype "Dd." Thus, 100% of their offspring would end up having dimpled cheeks, making choice e the correct answer.
