Answer:
The answer is A. There is more genetic variation in organisms that reproduce sexually than those that reproduce asexually.
Explanation:
This is because offspring with two parents can get genetics from both family's which means there is a chance for many different types of characteristics.
If an offspring only has one parent however, the offspring will only get those genetics from the parent which means there are not many possibilities for offspring to look or act different then their parent.
