write about significance of meosis

Answer 1

Heya!! ✌️✌️

Here is your answer dear....

One of the benefits of sexual reproduction is the diversity it produces within a population. That variety is a direct product of meiosis. Every sex cell made from meiosis has a unique combination of chromosomes. This means that no two sperm or egg cells are genetically identical.

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.

I HOPE THIS WILL HELP YOU OUT....

HAVE A GREAT DAY DEAR....
