Phenotypic

Definition:

The term "phenotypic" refers to the observable physical or biochemical characteristics of an organism, as determined by both genetic and environmental factors.

Study Guide:

To understand phenotypic characteristics, it's important to explore the following key points:

1. Genetic Basis: Discuss how an organism's genotype (genetic makeup) influences its phenotype. This can include traits such as eye color, height, and blood type.
2. Environmental Influences: Explain how environmental factors like nutrition, temperature, and exposure to toxins can also impact an organism's phenotype.
3. Observable Traits: Provide examples of observable phenotypic traits in humans, animals, and plants, such as hair color, leaf shape, or behavior.
4. Phenotypic Variation: Discuss how phenotypic variation within a species can result from genetic diversity and environmental differences.
5. Role in Evolution: Explore how phenotypic variations contribute to natural selection and the adaptation of species to their environments.
