Detailed explanation-1: -The combinations PP, PP, and pP have the same phenotype-purple flowers. This is because each contains at least one dominant allele (P). Only one combination, pp, produces plants that have white flowers. The ratio of dominant to recessive is 3:1, just as Mendel calculated from his data.

Detailed explanation-2: -Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

Detailed explanation-3: -Definition. 00:00. … Gene–environment interaction refers to the interplay of genes (and, more broadly, genome function) and the physical and social environment. These interactions influence the expression of phenotypes.

Detailed explanation-4: -Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related. In a narrow “genetic” sense, the genotype defines the phenotype.
