DOK Level 1: Recall

Explain why alleles are considered alternate versions of the same instructions.

• Because they are different genes entirely.

• Because they are different versions of a gene that can result in different traits.

• Because they are identical copies of a gene.

• Because they are unrelated to genes.

How do alleles contribute to genetic diversity?

• By being identical in every individual

• By providing different versions of a gene

• By mutating frequently

• By being the same in both parents
