Genetic makeup is called?

• A. Genotype
• B. Phenotype
• C. Alleles
• D. Loci

Answer: (A)

Genotype is the genetic makeup—the specific alleles an organism carries for one or more genes. It’s the internal genetic constitution that can be homozygous (two identical alleles) or heterozygous (two different alleles). This genotype, together with environmental factors, helps shape the observable trait (phenotype). The other terms refer to different ideas: phenotype is what you can see or measure in an organism; alleles are the versions of a gene; and loci are the exact positions of genes on a chromosome. So the genetic makeup is the genotype.
