"Genetic makeup" usually means an organism's genotype or genome:

- Genotype: the specific set of genes and alleles an individual carries (e.g., having two copies of a brown‑eye allele vs one brown and one blue). It describes which versions of particular genes are present at each locus.
- Genome: the organism's entire DNA sequence — all of its genes and noncoding DNA (for humans, ~3 billion base pairs).

The genotype/genome provides the hereditary instructions that influence an organism's traits, but actual traits (the phenotype) result from interactions between that genetic makeup, the environment, and regulatory/epigenetic factors.
