Question

Which of the processes, sexual reproduction or asexual reproduction, brings about maximum variations in the offsprings?

Answer 1

1. The sexual reproduction is the processes that brings about the marked variation in the offspring.
2. The reason is that the sexual mode of reproduction involves contribution of a set of chromosomes from both the parents and hence more variation is produced.
3. In asexual mode of reproduction, only a single parent contributes both the sets of chromosomes and same set is transmited for generations together without variation.
4. So the variation introduced in the offspring is more in sexual mode of reproduction as compared to asexual mode.
5. So, because of the following following reason sexual reproduction causes variations:

• Involvement of two parents for the fusion of their gametes.
• Crossing over during gamete formation.
