Answer and Solution
Answer
C. It has both dominant and recessive alleles
Solution:
A 1:2:1 ratio suggests that individuals possess both dominant and recessive alleles, indicating that both types of alleles are present in the trait's inheritance. Thus, 'It has both dominant and recessive alleles' is the correct response. Other options misinterpret what the ratio indicates.
