Why is it necessary for gametes to be formed through Meiosis?
The formation of gametes during Meiosis, is arrive at half the original chromosome number i.e. Haploid (n). This allows for the gametes (also half chromosome number) from the other sex cell to fertilise it. Thus at fertilisation a full compliment of chrosomes are received from each parent. The new cell is hence diploid (2n). If meiosis does not occur one would have a doubling of the chromosome number continually, eg. 46(male) + 46(female)= 92(new individual) With meiosis,its 46(male) then meiosis= 23. 46(female), then meiosis=23.
