A recessive gene governs trait M. If a child exhibits trait M, then _____ trait M.

Question

Quizplus · Accepted Answer

Since trait M is governed by a recessive gene, both parents must have the recessive gene for the trait to be expressed in their child. Therefore, option B is the correct choice. Option A is incorrect because it is possible for one parent to carry the recessive gene without exhibiting the trait. Option C is incorrect because the child could inherit the recessive gene from both parents. Option D is incorrect because if the child had a dominant gene for the trait, then they would not exhibit the recessive trait M.
