Question

which of the following terms describes the letters that represent two alleles of a gene (ex. aa, aa, or aa)? homologous chromosomes trait phenotype genotype

Explanation:

The term "Genotype" refers to the genetic makeup of an organism, specifically the combination of alleles (e.g., AA, Aa, aa) that an individual has for a particular gene. Homologous chromosomes are pairs of chromosomes (one from each parent) that have the same genes at the same loci. A trait is a characteristic (e.g., eye color). Phenotype is the observable physical or biochemical characteristic resulting from the genotype and environmental interactions.

Answer:

Genotype
