Quizplus · Accepted Answer

A dominant gene is defined as a gene that controls the appearance of a certain trait. When an organism has both a dominant and recessive gene for a particular trait, the dominant gene will always be expressed in the phenotype of the organism. Mutated and recombinant genes do not necessarily control the appearance of a certain trait, and recessive genes are only expressed in the phenotype when an individual has two copies of the recessive gene.
