1. Write two points of difference between asexual and sexual types of reproduction. Describe why variations are observed in the offspring formed by sexual reproduction.

Soln:

Sexual reproduction	Asexual reproduction
Two parents are involved	Single parent is involved
Gametes are formed	Gametes are not formed

In sexual reproduction we can find more variations when compared to asexual mode of reproduction. Following are the reasons for that.

• Gene pool are contributed by two parents
• Crossing over that occur during meiosis results in more variation

• DNA replication also contributes for the variation
