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: -A phenotypic trait (simply trait or character state) is a distinct variant of an organism’s characteristic, and it is an obvious and measurable trait that is expressed in an observable way. For example, the eye color (green, blue, brown, and hazel) is a phenotypic trait which is a polygenetic inheritance.
Detailed explanation-4: -What is Phenotypic Expression? The phenotype of an organism is essentially gene expression that is visible to others (e.g. colour of hair).
Detailed explanation-5: -The physical expression of a gene is called phenotype. It represents the way we see an organism from outside. Genotype is the genetic make up of a cell. It is the genotype that determines the phenotype.
