Q
Why is meiosis necessary for gamete formation instead of mitosis?
A
Meiosis is necessary because it reduces the chromosome number in gametes (sperm and egg) to haploid (n), preventing chromosome doubling in each generation.
If gametes were made by mitosis, they would be diploid (2n).
Fertilization would result in a 4n zygote (polyploidy), disrupting normal development.
Meiosis halves the chromosome number, so fertilization restores the diploid (2n) number in offspring, maintaining genetic stability across generations.
