Question

Which statement explains the difference between multiple alleles and polygenic inheritance? A. Multiple allele means more than one gene contributes to the phenotype and polygenic inheritance means more than two forms of the same gene in the population. B. Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait. C.Multiple allele means more than two forms of different genes in the population and polygenic inheritance means one gene contributes to many phenotypic characters.

Answer 1

"Multiple allele means more than one gene contributes to the phenotype and polygenic inheritance means more than two forms of the same gene in the population" is the statement among the choices given that explains the difference between multiple alleles and polygenic inheritance. The correct option is option "A".

Answer 2

The correct answer is B. Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.

Polygenic inheritance ia type of inheritance pattern of any trait are being controlled by two or more genes which can be on the same chromosome or different chromosomes. In multiple allele inheritance the traits are controlled by more than two alleles. The polygenic inheritance has a major distinction with the Mendelian inheritance in which the traits are being determined by a single gene. The polygenic traits can have several possible phenotypes which are determined as a result of interaction between several alleles. The multiple alleles are present when the particular gene has more than two types of alleles. An example for multiple alleles can be the blood group type of the humans where a single gene controls the blood type an individual can have i.e. A, B or O allele.
