A defining characteristic of sympatric speciation is Group of answer choices a. The appearance of new species in the midst of old ones b. Asexually reproducing populations c. Geographic isolation. d. Artificial selection e. Large populations

Explanation:

The process or mechanism by which the formation of the new species takes place is called speciation. On the basis of factors and conditions, there are many ways in which the speciation takes place.
