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: -Examples of Phenotypes Humans have appearance phenotypes, too; for example, your height and your eye color are both phenotypes controlled, at least partly, by your genes. Behavior can be a phenotype, too.

Detailed explanation-4: -With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.

Detailed explanation-5: -A person’s genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient’s clinical presentation.
