Which statement is accurate? A. A gene consists of two traits. B. An allele is one form of a gene. C. Most alleles have many genes. D. An allele is made up of two genes.
A trait is usually determined by more than one gene, much less two traits, so A is false. Alleles are a form of a gene, and any genes have usually two alleles, not the other way around, so C and D are both false.
