Question

Quizplus · Accepted Answer

Phenotypes can vary depending upon the environment. Although genotypes provide the instructions for the development and functioning of organisms, the environment can affect the expression of genes and ultimately impact the phenotype. Factors such as nutrition, temperature, light, and other external stimuli can influence the way genes are expressed, resulting in different phenotypes even among organisms with similar genotypes.
