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: -(FEE-noh-tipe) The observable characteristics in an individual resulting from the expression of genes; the clinical presentation of an individual with a particular genotype.

Detailed explanation-3: -phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.

Detailed explanation-4: -An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics-which are influenced both by its genotype and by the environment.

Detailed explanation-5: -With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
