B) Genes are proteins that express traits. Alleles are sections of DNA that produce genes.

Answer 2

A gene is a sequence of DNA that can be translated into a protein.

An allele is a version of a gene. We have two alleles of every gene, located on the same spot on different chromosomes. For example, the gene for eyecolor can either be the allele blue or the allele brown, but they are the same gene!
