1. What is Meiosis?
2. What is the significance of meiosis? (any 2)
3. Why is meiosis called a reductional division?​

Answer 1

Explanation:

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. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. ...

1. What is Meiosis?

$\huge\pink{Answer:}$

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each paternal and maternal chromosome.

2. What is the significance of meiosis? (any 2)

$\huge\pink{Answer:}$

Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. It activates the genetic information for the development of sex cells and deactivates the sporophytic information. It maintains the constant number of chromosomes by halving the same.

3. Why is meiosis called a reductional division?

$\huge\pink{Answer:}$

The first division is called the reduction division – or meiosis I – because it reduces the number of chromosomes from 46 chromosomes or 2n to 23 chromosomes or n (n describes a single chromosome set). ... The two sperm cells split again producing four sperm cells, each with 23 or n chromosomes.
