NEETBotanyCell Cycle and Cell Division
What happens to the diploid phase in the life cycle of sexually reproducing organisms after meiosis?
Options
- AIt remains the same
- BIt increases
- CIt decreases
- DIt is restored by fertilization
Correct answer
D. It is restored by fertilization
Step-by-step solution
The production of offspring by sexual reproduction includes the fusion of two gametes, each with a complete haploid set of chromosomes. Gametes are formed from specialised diploid cells. This specialised kind of cell division that reduces the chromosome number by half results in the production of haploid daughter cells. This kind of division is called meiosis. Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms whereas fertilisation restores the diploid phase. We come
