Write two points of difference between asexual and sexual types of reproduction. Describe why variations are observed in the offspring formed by sexual reproduction
| Asexual reproduction | Sexual reproduction |
| (a) Involves only one parent | (i) Often involves two parents |
| (b) Gametes are not produced | (ii) Gametes are produced |
| (c) No fertilisation and zygote formation | (iii) Fertilisaton and zygote formation is observed. |
| (d) Meiosis does not occur at anytime during reproduction | (iv) Meiosis occurs at the time of gamete formation |
Variations are observed in the offspring formed by sexual reproduction,
because of
following reasons:
• Gene pool is contributed by two parents.
• Crossing over during meiosis results in variations.
• DNA replication also plays some role in variation.
