- In sexual reproduction, genetic variation occurs among the off springs, which may adapt better with the environment.
- Hence the statement is true for maximum.
- Progeny from asexual reproduction have similar genetic make up and are exact copies of their parents, i.e., clone of the parent.

- Progeny is less adaptable to changes in environment.
- Progeny from sexual reproduction have different genetic make up and are dissimilar to the parent.
- Variation occurs in progeny.
- Progeny is more adaptable to changes in environment
