<u>Dominant phenotypes</u> will manifest when either or both chromosomes have the same dominant alleles, whereas <u>recessive phenotypes</u> will only manifest when both chromosomes have the same recessive alleles. Dominant alleles are shown with a capital letter and the recessive allele with the corresponding small letter. Recessive alleles will be overridden by the presence of a dominant allele. Two recessive alleles (no dominant) need to be present for the recessive characteristic to be expressed in the phenotype .
