Which of the following best describes how the environment may play a role in the expression of our genes?
A) All genes are directly influenced by the environment, even if only in minor ways, so the environment will always alter phenotype for all genes.
B) Some phenotypes, including skin color, can be influenced by the environment. The genotype still determines some aspect of skin color, but the interaction with the environment, in the form of sun exposure, can cause variations in the resulting phenotype.
C) The environment is not able to alter genes or their physical expressions. Genotypes and phenotypes are both completely independent of environmental changes, unless in the form of mutations.
D) The environment can alter an individual's appearance, but because these changes are temporary and unable to be inherited, they have no impact on the genotype or the expression of that genotype.
