What is genotype?

Genotype refers to the genetic makeup of an organism, specifically the combination of alleles present for a particular trait.

It represents the information encoded in the genes that an individual inherits from its parents. The genotype determines how a trait can be expressed, although the actual expression may also be influenced by environmental factors.

For example, a person may have alleles for tall height (genotype), but the final height (phenotype) can vary depending on nutrition and other conditions.

Genotype plays a crucial role in heredity, variation, and the study of genetics.
