Multiple Choice

Which of the following best describes the difference between alleles and genes?

• Alleles are genetic variants of the same gene; they code for different versions of the same characteristic.

• Genes are only found in plants, while alleles are found in animals.

• Genes and alleles are exactly the same thing.
