Which statement correctly compares the inheritance of blood type in humans and the inheritance of length of ears in corn plants? a. blood type is controlled by multiple forms of a single gene, while the length of corn ears is controlled by many different genes. b. blood type is controlled by many different genes, while the length of corn ears is controlled by multiple forms of a single gene. c. both blood type and the length of corn ears are controlled by multiple forms of a single gene. d. both blood type and the length of corn ears are controlled by many different genes.

The correct answer is a. Blood type is controlled by multiple forms of a single gene, while the length of corn ears is controlled by many different genes.

a. Blood type is controlled by multiple forms of a single gene, while the length of corn ears is controlled by many different genes.

Polygenic inheritance refers to a single inherited phenotypic trait that is controlled by two or more different genes.

Polygenic inheritance should not be confused with the effects caused by multiple alleles. In the case of multiple alleles, a gene contains several different allele variants on the same locus of each chromosome, for example the three different alleles which control for blood type – A, B & O.
