Expert Answer
Dear Student,
Sexual reproduction leads to genetic variation in offspring by three mechanisms-
(i) Independent assortment
(ii) Crossing over
(iii) Random fertilization
It is important to keep in mind, however, that the ultimate root of all variations is mutation.
We hope that clarifies your query.
