What is the importance of haploid cells?

1.	What is the importance of haploid cells?
Answer» 1. The gametes that take part in the sexual reproduction should be haploid. 2. Otherwise the chromosome number will not be maintained at constancy. E.g. Parents have 2n = 46 chromosomes in their cells. 3. If meiosis does not take place in them, the gametes formed will also contain 46 chromosomes. 4. The resultant offspring will have 46 + 46 = 92 chromosomes. 5. Such skewed number will produce large scale abnormalities. 6. But due to meiosis, the gametes formed are haploid and thus the chromosome number is maintained constant for every species. Gametes are haploid cells, this is the most important fact.
