What is an allele?

• A complete set of an organism's DNA

• Different forms of a gene that can produce variations in traits

• A change in the DNA sequence

• The physical traits of an organism.

What does the genome of an organism include?

• Only the genes

• The complete set of an organism's DNA, including all of its genes

• Only the physical traits

• Only the alleles.
