Detailed explanation-1: -The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

Detailed explanation-2: -With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.

Detailed explanation-3: -Phenotype is the observable physical or biochemical characteristics of an individual organism, determined by both genetic make-up and environmental influences, for example, height, weight and skin colour.

Detailed explanation-4: -Many physical traits like hair color and texture, eye color, and skin color are determined by the genotypes that parents pass down to their children. In one sense, the term “genotype”-like the term “genome”-refers to the entire set of genes in the cells of an organism.

Detailed explanation-5: -A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.
