What type of organism typically displays a phenotype resulting from its genotype?

A phenotype refers to the observable traits or characteristics of an organism, which result from the interaction between its genotype (the genetic makeup) and the environment. Multicellular organisms, such as plants and animals, typically display a phenotype that is directly related to their genotype. This is because the complexity of their genetic information can express various traits through multiple interactions between different genes and environmental factors.

In multicellular organisms, different cells can express different genes, leading to specialization and diversity in phenotypes, such as leaf shapes in plants or skin color in animals. This complexity highlights the relationship between genotype and phenotype, allowing for a wide variety of observable traits.

In contrast, while single-celled organisms can also express phenotypes based on their genotypes, the range of phenotypic expression is often less complex due to their simpler structures. Prokaryotic organisms, which include bacteria, have even more straightforward genetic interactions and may not always display varied phenotypes in a way that shows the depth of genotype influence seen in multicellular organisms. Thus, the best representation of the relationship between genotype and phenotype is found in multicellular organisms.
