Vysvětlení
A dominant allele is a trait that is always expressed in an organism's phenotype, as long as at least one copy of the allele is present. An organism's observable traits are called its phenotype, while its underlying genetic makeup is called its genotype. A person's phenotype is determined by both their genotype and environmental factors.
