Which is a better mode of reproduction: sexual or asexual? Why?
Offspring formed due to sexual reproduction have better chances of survival. Why? Is this statement always true?
1. The process involves only one cell or one parent.
2. The whole body of the parent may act as reproductive unit or it can be single cell or a bud.
3. The offsprings are genetically similar to parent.
4. Only mitotic division takes place.
5. No formation of sex organs.
6. No evolutionary significance.
1. This process involves two cells or gametes belonging to either the same or different parents.
2. The reproductive unit is called gamete
which is unicellular and haploid.
3. The offsprings differ from parents.
4. Meiosis and mitosis both take place.
5. Formation of sex organs is essential.
6. It introduces variation hence of evolutionary significance.
(ii) Vegetative reproduction is also considered as a type of asexual reproduction because it does not involve fusion of male and female gametes and require only one parent. New plants are produced by vegetative parts of plants without the formation of seeds or spores .
