Question

Based on the diagram, how do planarians benefit from sexual reproduction? (see pic)

Answer 1

The correct answer would be "sexual reproduction increases the genetic variation".

Sexual reproduction involves the involvement of two parents.

It involves the formation and fusion of gametes which are contributed by both the parents.

Therefore, the genome of the offspring is contributed by both the parents due to which the genetic diversity in the offspring produced by sexual reproduction is more as compared to the offspring produced by a single parent or asexual reproduction.

Answer 2

This question have choices.
A) Sexual reproduction is simpler and requires less energy than asexual reproduction.
B) Sexual reproduction produces genetic variation in offspring.
C) Sexual reproduction does not benefit planarians since asexual reproduction is an alternative.
D) Sexual reproduction creates genetically identical offspring.

Planarians benefit from sexual reproduction because B.) sexual reproduction produces genetic variation in offspring.
