Give two reasons for the appearance of variations among the progeny formed by sexual reproduction.

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.
