In genetics, what is an allele?
A
A segment of DNA that codes for multiple unrelated traits in different organisms

Understand that a gene is a segment of DNA that codes for a specific trait.
Recognize that an allele is a variant form of a gene that exists at the same locus (position) on homologous chromosomes.
Note that different alleles can result in different expressions of a trait, such as eye color or blood type.
Distinguish alleles from other genetic concepts: they are not entire genes, cell division processes, or physical locations themselves.
Conclude that an allele is best defined as an alternative version of a gene found at a specific locus on a chromosome.
