What are the inherited factors transmitted in an organism from generation to generation called?

Inherited factors that are passed from parents to offspring are known as an organism’s genotype. The genotype refers to the genetic makeup of an organism, including the specific alleles inherited for each trait. Heterozygote and homozygote describe specific combinations of alleles but do not refer to inherited factors as a whole. Phenotype refers to the observable traits of an organism, which result from the interaction between genotype and environment. The NEX Science exam often tests the distinction between genotype and phenotype, emphasizing that genotype represents the genetic instructions while phenotype represents the physical expression of those instructions.
