Studies on heritability concern the degree to which variation in the observable traits of a person, or phenotype, can be attributed to variation in the genotype, or underlying genetic structure.
Step-by-step explanation:
The differentiation between genotype – phenotype is taken from genetics. Genotype is the complete genetic knowledge about an organism. Phenotype is the specific observable features of an organism such as morphology, evolution, or behavior. This contradiction is central to the analysis of trait inheritance and its evolution.
The potential genotypes for the flower-colored gene were red-red, red-white and white-white, for instance, in pea plants. Phenotype is the physical expression of the allele-shaped mutation (genotype) of a species.
