[productkeypro]

A dominant gene is a type of gene that masks the effect of a recessive gene. It is the version of a gene that will always appear when present in an organisms genotype, regardless if its paired with a recessive gene in a heterozygous pair. Its trait will be physically exhibited, determining the particular characteristic or disorder in an organism.
