Can you describe the difference between a dominant trait and a recessive trait?

Explanation:

A dominant trait is a genetic trait which will manifest when only one copy of the gene is present, overriding another inherited gene coding for a different version of the trait.eg Dark hair. Whilst recessive traits are being or produced by a form of a gene whose effect can be hidden by a dominant gene and which can produce a noticeable effect only when two copies of the gene are present Blue eye color is a recessive trait.
