A dominant allele is one that results in a dominant trait when present in an individual's genotype. This means that even if an individual only inherits one copy of the dominant allele, they will express the dominant trait. In contrast, a recessive allele is only expressed when an individual inherits two copies of the recessive allele. Therefore, the presence of a dominant allele results in a dominant phenotype, which is what makes it "dominant."
