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

A.
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.

B.
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.

C.
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.

D.
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.

The answer is D. 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.

A gene is a section of a chromosome that code for a particular protein which determines some phenotypic traits. Every organism contains two alleles for a trait, so the alleles are alternative forms of a gene.
For example, for a trait there are two variations, or two alleles - A and a. But, the genes are AA or Aa or aa. So, the section of a chromosome will determine eye color, for example. This section represents a gene for eye color. Still, there is no only one eye color. The gene for eye color has many different variations which are called alleles. There are alleles for black, brown, blue, etc. eye colors.
