Question

which of the following is not a significance of meiosis ??
a, formation of gametes
b, Increases genetic variability
c, Reduction of chromosome number to half
d, replaces old dead and worn out cells....


please answer this along with reason ​

Answer 1

Answer:

The answer is D.replces old dead and worn out cells.

Explanation:

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. so replaces old dead and worn out cells Is not a significance of meiosis.

Answer 2

Of the following option, d - replacing old dead and worn-out cells is not significance for meiosis.

• As we are aware, meiosis is also known as reductional division since it involves a reduction in chromosome number from the parent cell to the daughter cell by 50%. DNA replication only occurs once during each of the two cycles, Meiosis I and Meiosis II, which entail nuclear and cell division.
• It is in the process of mitosis where the process replaces old dead and worn-out cells.
• Hence, option d is incorrect.
