Phenotype in biology definition
Web16. jún 2024 · In biology, it refers to the quantitative inheritance wherein two or more independent genes additively affect a single phenotypic trait. In a way, polygenic inheritance is a multiple factor inheritance or multiple gene inheritance, or multifactorial inheritance. WebA phenotypic trait is an obvious, observable, and measurable characteristic of an organism; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color or eye colour. Underlying genes, which make up the genotype, determine the hair color, but the hair color observed is the phenotype.
