Verified by Toppr

During favourable conditions, algae and fungi multiply asexually but during unfavourable conditions, gametes are formed. The gametes fuse to form zygotes which often develop a thick wall to become zygospores, which are dispersed. Under favourable conditions zygospore germinates to form new organisms. Sexual reproduction induces variations which may help in survival of organism.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
