Which term describes an organism's genetic makeup?

Explanation:
Genotype is the genetic makeup—the specific genes and alleles an organism carries. It acts as a blueprint that, together with the environment, helps determine traits. Observable traits form the phenotype, which can differ from the genotype because of environmental influences. Chromosomes are the carriers that hold genes, not the makeup itself, and genetic variation refers to differences in DNA among individuals rather than the makeup of one organism.
