Question

in order for new functions to arise, what must happen after gene duplication events? mutations must occur in one copy of the gene or in its regulatory region both copies of the gene must become non - functional both copies of the gene must stay the same as each other one copy of the gene must be passed on, but the other must not one copy of the gene must be transcribed, but the other copy must not

Explanation:

After gene duplication, for new functions to arise, mutations in one copy of the gene or its regulatory region can lead to changes in gene - product function or expression pattern. Non - functional genes won't give new functions, identical copies won't create novelty, and passing on or transcribing one copy without change won't generate new functions.

Answer:

Mutations must occur in one copy of the gene or in its regulatory region
