Naturally Occurring Diversity and Its Environmental Impact on Phenotypes

Genetic diversity within biological systems is a key driver of variation in traits and behaviors among organisms. The same genotype can produce multiple phenotypes depending on environmental conditions, illustrating the complexity of gene-environment interactions. This phenomenon, known as phenotypic plasticity, reflects the ability of an organism to express different phenotypic traits under varying environmental influences, even if the underlying genetic makeup remains unchanged.
