What is a genotype?

A genotype refers to the genetic constitution of an individual organism. It encompasses the specific alleles (versions of genes) that an organism possesses, including both dominant and recessive forms. This genetic information can dictate various traits and characteristics, although the actual manifestation of those traits is influenced by other factors such as the environment and interactions with other genes.

Understanding the concept of a genotype is fundamental in genetics as it provides the basis for genetic variation within a population and allows for the study of heredity. The genotype can be instrumental in predicting potential physical attributes, behaviors, and susceptibilities to diseases in organisms, but it is distinct from the observable traits or phenotypes that result from the expression of the genotype in a given environment.
