Question

Quizplus · Accepted Answer

The dominant-recessive genes principle states that a recessive gene exerts its influence only if the two genes of a pair are both recessive. If one gene is dominant, it will mask the effect of the recessive gene. Therefore, option A is incorrect. Blonde hair, nearsightedness, and freckles are examples of dominant traits, making option C incorrect. Brown hair, farsightedness, and dimples are examples of recessive traits, making option D partially correct, but option B is the best choice as it fully captures the principle.
