    Which genetic modification could increase the yield of crop measured as mass of crop produced per unit area per year?

    A) Herbicide resistant plants

    B) Delayed ripening in the fruits

    C) More essential amino acids in the seeds

    D) More vitamin-A in the grain

    Correct Answer: A

    Solution :

    Genetic modification of plants into herbicide resistant plants can improve crop yield. This is because herbicides are used to get rid of weeds which compete with crops for soil nutrients. Transgenic plants are not inhibited by herbicide. Thus, farmers may apply a specific herbicide to control weeds population, without damaging their herbicide tolerant crops. This leads to an increase in crop yield because of less competition from weeds.
