Question

Give the significance of fertilization.

Answer 1

Hint: Fertilization Is the process of fusion of gametes. That helps to form new characteristics in the offspring.

Complete Answer:
- The gametes come from male and female and then combine.
- During gamete formation, the number of chromosomes is reduced to half so that when the two of them combine the whole number of chromosomes is restored.
- It means the gametes are haploid and when the fusion occurs it becomes diploid.
- This haploid and diploid nature helps to make sure that the correct number of chromosomes is present in it.
- This fusion leads to the mixing of genes and the new organism has some similarities with some new types of variations. This process helps in getting genetic variations in the ecosystem that leads to formation of new types in the environment.

Note: It is noted that fertilization occurs mostly inside the female bodies except in some cases where the fertilization and the development occur inside the male bodies. It can also be said as the union of gametes such as eggs and sperms in humans. Egg is the female reproductive structure and sperm is the male reproductive structure.
