Which statement best describes the difference between a gene and an allele?

A.
A gene is a section of a chromosome that typically contains the code for a particular protein. An allele is one of two or more alternative forms of a gene.

B.
An allele is a section of a chromosome that typically contains the code for a particular protein. A gene is one of two or more alternative forms of an allele.

C.
A gene is a section of DNA , which typically contains the code for a specific protein that determines a specific trait. An allele is a section of a gene.

D.
An allele is a section of DNA , which typically contains the code for a specific protein that determines a specific trait. A gene is a section of an allele.

A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. For example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes.

An allele is found at a fixed spot on a chromosome. Chromosomes occur in pairs so organisms have two alleles for each gene — one allele in each chromosome in the pair. Since each chromosome in the pair comes from a different parent, organisms inherit one allele from each parent for each gene. The two alleles inherited from parents may be same (homozygous) or different (heterozygotes).
