If a single gene has 3 or more alternative forms,this is called

E)codominance.

Question

Quizplus · Accepted Answer

When a single gene has three or more alternative forms, it means that there are multiple alleles for that gene. Pleiotropy refers to a gene that affects multiple traits, epistasis refers to the interaction of genes, blending inheritance was a discredited theory of inheritance, and codominance refers to both alleles being expressed in the phenotype. Therefore, the best choice for this scenario is multiple alleles.
