Question

How sexual reproduction enables simpler organisms to survive during unfavorable conditions?

Answer 1

Variation in sexual reproduction:

1. The event of crossing over occurs during meiosis, which alters the genetic character of the organism.
   
2. ​After meiosis, the gametes are produced which fuse together to form zygotes.
   
3. This crossing over leads to variation and the changes in genetic character helps the organism survive in adverse conditions.
   
4. Therefore, using sexual reproduction the simpler organisms can survive and adapt easily ti the adverse environment.
