Quizplus · Accepted Answer

A gene that only influences the expression of a trait when paired with another less active gene is called recessive. This means that the trait will only be expressed if there are two copies of the recessive allele present. If there is at least one dominant allele present, the trait will be expressed regardless of whether a recessive allele is also present.
