The correct answer is A. Quantitative traits
Explanation:
In genetics, quantitative traits refer to traits or phenotypes (observable traits) that depend on many factors including multiple genes and actions in the environment. These traits differ from other traits because the traits tend to be more diverse in a population. In the case presented, the shell color in clams is an example of a quantitative trait because this phenotype is the result of three different each and each gene contains two alleles which means the color depends on many factors. Additionally, as most quantitative traits there is a higher variation in the phenotype considering clams can have different hues.
