Answer:
The correct answer would be D.) It is carried out in cells that are involved in sexual reproduction.
Meiosis is type of cell division which results in the formation of four haploid cells from single diploid parent cell.
It is also celled reductional division as it reduces the number of chromosomes to half in all the daughter cells.
It is divided into two stages meiosis I and meiosis II. Meiosis I includes division of homologous chromosomes which results in the formation of 2 haploid daughter cells from one parent cell.
The two daughter cells undergo meiosis II during which sister chromatids are pull apart which results in the formation of 4 daughter cells each containing half the chromosomes of parent cell.
It takes place in cells that are involved in sexual reproduction that is, it results in the formation of haploid gametes from diploid precursor cells.
In males, it results in the formation of sperm cell and in females it helps in the formation of eggs.
In sexual reproduction, fusion of gametes results in the formation of diploid zygote that is, re-storage of diploid chromosome number.
