Solution
A heterozygote has a pair of non-identical alleles for the trait being studied.
Explanation:
A heterozygote has two different alleles at a gene locus for the trait being studied. This means it carries a pair of non-identical alleles (one from each parent). The condition is diploid, not haploid, because haploid means having a single set of chromosomes, which does not apply here. Homozygotes have identical alleles, while heterozygotes have non-identical ones for the trait of interest.
