Verified step by step guidance1
Understand the definition of heterozygous: an organism is heterozygous for a gene if it has two different alleles for that gene.
Identify the alleles given: the gene has two alleles, represented as 'A' and 'a'.
List the possible genotypes: 'AA', 'Aa', and 'aa'.
Determine which genotype contains two different alleles: 'Aa' has one dominant allele 'A' and one recessive allele 'a', making it heterozygous.
Conclude that the heterozygous genotype for the gene with alleles 'A' and 'a' is \(\text{Aa}\).
