Genetic traits that require two copies (one from each parent) to be expressed in the offspring. If only one copy is present, the trait will not manifest because it is masked by a dominant gene.

Dominant Genes

These are genes that are expressed over other genes, called recessive genes, in determining certain traits in an organism.

DNA
