Pairs of alleles that are different are referred to as _______.

Solution
The correct term to fill in the blank is heterozygous.

- Homozygous: This term refers to a pair of alleles that are the same. For example, both alleles could be for brown eyes (BB) or both could be for blue eyes (bb).
- Heterozygous: This term is used when the two alleles are different. For instance, one allele could be for brown eyes (B) and the other for blue eyes (b), making the pair heterozygous (Bb).
Thus, pairs of alleles that are different are referred to as heterozygous.
