Detailed explanation-1: -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-2: -With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
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: -Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex. Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays.
Detailed explanation-5: -The phenotype is an observable or identifiable trait that is coded for by the genotype. This could be biochemical or physical. Phenotypes are not completely defined by the genotype. Other factors such as the environment can affect the observable traits.
