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.

The 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.

An allele is one of two or more alternative forms of a gene. So, m ultiple allele means more than two forms of the same gene in the population.

Polygenic inheritance is responsible for traits that are controlled by two or more genes. The name itself explains the meaning: poly means many, so literally it means many genes.
