Why is it necessary for chromosome number to be halved during meiosis? ?

Question

What would happen to offspring if this reduction in chromosomes number didnt occur?

Answer 1

Well, since you get one set of chromosome from your mother and one from your father, you need to only get half from each to get a full set total.

If you were to get a full set from both, you would have double the amount of chromosomes you need (and would die).

Answer 2

chromosome number has to be halved bcoz the contribution from each parents.

Female (n) mate with male (n) will have offsprings (each of them is n+n=2n).

if the reduction of number doesn't occur that means....for example 2n + n equals.......3n or so. This causes a gene mutation.
