Genotype refers to the genetic makeup of an individual organism, which includes all the genes and alleles present in its DNA. This term is commonly used in genetics and biology to describe the specific genetic information that an organism inherits from its parents. Genotype can influence various traits and characteristics of an organism, such as physical appearance, behavior, and susceptibility to diseases. Researchers in this area study the relationship between genotypes and phenotypes, as well as how genetic variations can impact individual differences and evolution within populations. The study of genotypes is essential for understanding genetic inheritance, heredity, and the underlying mechanisms of genetic diseases.
