Verified step by step guidance1
Understand that in genetics, a gene is a segment of DNA that codes for a specific trait or function.
Recognize that an allele is a variant form of a gene that exists at a particular position, called a locus, on a chromosome.
Know that different alleles can result in variations in the trait that the gene controls, such as different eye colors or blood types.
Distinguish alleles from other genetic concepts: they are not proteins, entire chromosome sets, or physical traits themselves, but rather the specific versions of a gene.
Summarize that an allele is best defined as an alternative form of a gene found at a specific locus on a chromosome.
