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: -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-3: -(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-4: -With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
Detailed explanation-5: -A phenotype includes traits visible to the eye, such as height, eye and hair color, and so on. It also includes less obvious traits, such as metabolic rate and organ function. Phenotypes reflect a combination of genes and environment.
