Definitions:

Additive Alleles

Alleles that contribute to the phenotype in an additive manner, where the effect of multiple alleles simply adds up.

Dominant Alleles

Alleles that express their phenotype even when paired with a different allele in a heterozygous genotype.

Recessive Alleles

Genetic variants that must be inherited from both parents to be expressed in the offspring; not expressed when a dominant allele is present.

Genetic Drift

Genetic drift refers to random fluctuations in the frequencies of alleles (variant forms of a gene) within a population, which can lead to the increase or decrease in certain traits over time.
