Write two points of difference between asexual and sexual types of reproduction. Describe why variations are observed in the offspring formed by sexual reproduction.
(N/A)
During sexual reproduction,two types of gametes fuse. Although the gametes contain the same number of chromosomes,their $DNA$ is not identical due to the process of recombination during meiosis. This genetic shuffling generates variations among the offspring.
| Asexual reproduction | Sexual reproduction |
|---|---|
| $(a)$ Involves only one parent. | $(i)$ Involves two parents of opposite sex. |
| $(b)$ Gametes are not produced. | $(ii)$ Gametes are produced. |
| $(c)$ No fertilization and zygote formation occurs. | $(iii)$ Fertilization and zygote formation are observed. |
| $(d)$ Meiosis does not occur. | $(iv)$ Meiosis occurs during gamete formation. |
