The combination of alleles on homologous chromosomes that determines a trait is known as what?

Explanation:
Genotype is the combination of alleles for a given gene on the two homologous chromosomes in a diploid organism. You inherit one allele from each parent, so your genotype for that gene is the specific pair you carry. This genetic makeup helps determine the trait that can be expressed as the phenotype, though environment can influence how it shows up. For example, a gene with alleles A and a can yield genotypes such as AA, Aa, or aa, and the corresponding phenotype depends on how those alleles interact. The genotype is different from the genome, which is the entire set of genetic material, and from an allele, which is a single variant of the gene.
