Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why do we need meiosis?
A
To double the number of chromosomes going into sex cells
B
To halve the number of chromosomes going into sex cells
C
To triple the number of chromosomes going into sex cells
D
To not change the number of chromosomes going into sex cells
Explanation: 

Detailed explanation-1: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-2: -We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Detailed explanation-3: -Meiosis produces cells with half the chromosomes to maintain genetic integrity in the offspring. During sexual reproduction a sperm and egg combine to make a new cell called a zygote. During this process of fertilization the genomes of the sperm and egg fuse.
