Offspring formed by sexual reproduction exhite more variation than those formed by asexual reproduction because :

Offspring formed by asexual method of reproduction have greater similarity among themselves because (i) Asexual reproduction involves only one parent (ii) Asexual reproduction does not involve gametes (iii) Asexual reproduction occurs before sexual reproduction (iv) Asexual reproduction occurs after sexual reproduction

What is a clone? Why do offsprings formed by asexual reproduction exhibit remarkable similarity?
