Shell color in clams is thought to be controlled by three different genes (each with two alleles). Shell coloration runs a range
sergejj [24]

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.

3. The mechanism in which organisms best suited for their environment survive<br> and reproduce.
lys-0071 [83]

The mechanism in which organisms best suited for their environment survive

and reproduce <u>NATURAL SELECTION.</u>

<u></u>

Explanation:

When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and  reproducing to passing down their genes to the next generations.

Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.
