Assertion: Probability of survival of an organism produced through sexual reproduction is more than that of organism produced through asexual mode.

Reason: Variations provide advantages to individuals for survival.

 

Answer:

(a) Both Assertion and Reason are true and R is the correct explanation of A

During sexual reproduction, there is a fusion of male and female gametes of the parents resulting in an offspring having a combination of genetic material which comes from both the parents. This provides a survival advantage to such offspring as compared to those which are produced by asexual reproduction and are genetically similar to the parent.
