A desert plant called Kalanchoe can reproduce, either with sexual reproduction through flowers, or asexually by budding off miniature leaf and root clusters from its leaves. When buds are produced, they land on the ground, take root, and grow, genetically identical to the original. If budding is used for several years, a large area may be covered with these descendents from the same original plant. The resulting population of plants will
A. automatically experience more genetic mutations, so that some of the plants will survive environmental change. B. None of the answer choices is correct. C. be more strongly able to adapt to environmental change, compared to the Kalanchoe that are reproducing sexually. D. not be as strongly able to adapt to environmental change, compared to the Kalanchoe that are reproducing sexually. E. adapt to environmental change, by shifting from asexual budding to conjugation, so they can sexually reproduce.
