He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above.

A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic |

Answer» rect OPTION is c)decreased its genetic diversityExplanation:Genetic diversity refers to the variations which can be FOUND in members of a species.Genetic diversity allows a species to be BETTER ADAPTED to survive.The lesser the genetic diversity, the more are the chances for a species to become endangered or extinct.In the above example, as Ralph started breeding only the purple flowers, the white flowered pea plant started to decrease and a completely end by the last breeding. |
