Maintenance of the normal quantity of chromosomes, Biology

Assignment Help:

Q. Why is meiosis significant for the maintenance of the normal quantity of chromosomes of a species with sexual reproduction?

A reduction to a half of the maximum normal quantity of chromosomes is compulsory in some phase of the life cycle of a species that reproduces sexually. If that could not occur in each generation, whenever a zygote is formed by fusion of gametes there would be duplication in the quantity of chromosomes in a geometric progression.
