Quizplus · Accepted Answer

The more influential member of a gene pair is called the dominant gene. It is the gene that is expressed even if only one copy is present in the organism's genotype. In contrast, the recessive gene will only be expressed if both copies are present. Therefore, the dominant gene is more influential in terms of expressing a trait.
