Detailed explanation-1: -Mendelian inheritance is involved when one particular gene controls for a trait, and the traits are discrete.

Detailed explanation-2: -Polygenic Trait A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance.

Detailed explanation-3: -Single-gene traits include some of the most observable physical traits in humans, like eye color, widow’s peak hairline, earlobe type (attached versus detached), presence of freckles or dimples, or the ability to roll your tongue.

Detailed explanation-4: -Discrete traits are those which maintain a distinct phenotype. For example, mouse eye color, which can be black or red, is a discrete trait. Quantitative traits are those in which a phenotypic range is observed throughout the population.

Detailed explanation-5: -Quantitative traits are also called continuous traits, and they stand in contrast to qualitative, or discontinuous, traits that are expressed in the form of distinct phenotypes chosen from a discrete set. Continuous variation in the expression of a trait can be due to both genetic and non-genetic factors.
