Understanding Scientific Terminology Quiz

What is the significance of the fact that different alleles are found on the same locations on the chromosomes of different individuals?

It allows organisms to have a wide variety of allele functions (correct)
It ensures that organisms have a uniform genetic structure
It results in a high likelihood of genetic mutations
