Mendel's Law of Dominance and Uniformity

The Law of Dominance and Uniformity states that some alleles are dominant over other alleles for a given gene. Alleles are different versions of a particular gene which are found at the same chromosomal location. Alleles can either be dominant or recessive and are noted with a capital letter if dominant and small letter if recessive. If an organism inherits 1 or 2 dominant alleles, the dominant trait, called phenotype, will be expressed. Only if an organism inherits 2 recessive alleles will the recessive trait be expressed.
