Answer:
Skin color is a quantitative trait influenced by the combined action of many genes, thereby different gene pools can result in the same skin color.
Explanation:
Quantitative traits (also known as continuous traits, ) are phenotypic traits that depend on the combined action of many genes and the environment. These traits show continuous variation, changing gradually over a range of values in the population. Examples of quantitative traits include height, skin color, weight, etc. A gene pool is the sum of all the individual genes in a population. In consequence, different populations may show different allele combinations (gene pools) that result in the same phenotype for a quantitative trait (skin color).

Mechanical weathering is the physical breakdown of rock into smaller pieces. Mechanical weathering breaks rocks down into smaller pieces. This gives the rock a larger surface area for chemical reactions to take place. Chemical weathering is the breakdown of rock by chemical processes.
