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: -The terms Genotype and phenotype may sound similar, but there is a huge difference between genotype and phenotype. The genotype is a set of genes in DNA responsible for unique traits or characteristics, while the phenotype is the physical appearance or characteristic of an organism.
Detailed explanation-3: -Polygenic inheritance can be explained by additive effects of many loci: if each “capital” allele contributes one increment to the phenotype. With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
