Answer:
The correct answer is a. lower
Explanation:
The genetic diversity of domesticated crop plants and animals is generally lower than that of wild plants and animals because in domesticated plants human reduces the genetic diversity by selecting and reproducing only those individual who have some particular trait that is beneficial for humans.
So by selfing these crops and animals, genetic diversity gets reduced in them as compared to wild plants. This reduces the genetic diversity because many other important traits which were present in wild type lost during time in domesticated crop.
