===Meaning===
A '''Dominant allele''' is an [[allele]] which can be expressed in the [[phenotype]] when there is only one copy of that [[allele]].
===About Dominant Alleles===
: When a [[genotype]] includes one '''dominant allele''' and one [[Recessive Allele|recessive allele]] the physical appearance of the person will be based on the '''dominant allele'''.
: In a [[Punnett Square]] or [[Genetic Cross Diagram]] '''dominant alleles''' are written with a capital letter while the [[Recessive Allele|recessive alleles]] are written with a lower case letter.
