Here's a breakdown:

* Phenotype: The observable characteristics of an organism, including its physical appearance, development, and behavior. These characteristics are a result of the interaction between an organism's genotype (its genetic makeup) and the environment.

* Genotype: The genetic makeup of an organism, represented by the combination of alleles (alternative forms of a gene) it possesses.

For example:

* Genotype: A person might have the genotype "BB" for eye color, meaning they have two dominant alleles for brown eyes.

* Phenotype: This person's phenotype would be brown eyes.
