Genotype refers to the genetic constitution of living organisms, which determines the various genetic traits of the organism.
The genotype of an organism states the hereditary potentials and restrictions from foetal stage during pregnancy through adulthood. Genotype is the total sum of genes transferred from parents to offspring. Hence, the genotype of a particular person is their own personal genetic make up. The genotype is expressed when information from genes’ DNA is utilized to make proteins and RNA molecules.
It is a known fact that all individuals consist of large amounts of DNA. But not all DNA is the same, and there is variation in the sequence of DNA amongst individuals. But when these particular differences in sequences are applied to a single gene, it is called genotype. Therefore, genotype is simply the unique version of DNA sequence that an organism has.
