The significance of meiosis lies in

a) reduction of diploid no. of chromosomes to haploid

b) maintaing constancy in no. of diploid chromosomes during sexual reproduction

c) production of genetic variability in population of species

d) all of above

which one is correct?

The significance of meiosis :-

1. It maintains the same chromosome n umber in the sexually reproducing organisms. From a diploid cell, haploid gametes are produced which in turn fuse to form a diploid cell.

2. It restricts the multiplication of chromosome number and maintains the stability of the species.

3. Maternal and paternal genes get exchanged during crossing over. It results in variations among the offspring.

4. All the four chromatids of a homologous pair of chromosomes segregate and go over separately to four different daughter cells. This leads to variation in the daughter cells genetically.
