Question

Quizplus · Accepted Answer

A recessive gene only exerts its influence (or is expressed in a phenotype) when both of the genes in the pair are recessive. In other words, if even one dominant gene is present, it will mask the effects of the recessive gene. The presence or absence of the dominant gene does not impact the strength of the recessive gene. The environment can also affect gene expression, but it is not specifically related to whether a gene is dominant or recessive.
