genotype

n. 1. The genetic makeup of an individual. This is opposed to the phenotype, which is the actual body of an individual, which is influenced both by genetics and interaction with the environment so that two individuals with the same genotype will have differences due to both the uterine and postuterine environments. Thus some people who have had their pet cats cloned have been surprised to find they do not have the same color fur nor the same disposition as their original pets had. 2. The particular variant of a gene possessed by an individual.
