Question

In a parent cell with 2n number of chromosomes, at the end of telophase I ___(i)___ are formed and at the end of telophase II ___(ii)___ are formed.

• A. (i) four diploid cells; (ii) four haploid cells
• B. (i) two diploid cells; (ii) four haploid cells
• C. (i) a dyad of cells; (ii) four haploid cells
• D. (i) four haploid cells; (ii) a dyad of cells

Answer 1

The correct option is C (i) a dyad of cells; (ii) four haploid cells

Meiosis is a type of cell division that occurs in sexually reproducing organisms which reduces the chromosome number by half, resulting in the formation of haploid daughter cells. The ploidy of the cells at the end of meiosis I and meiosis II is given in the image below.


During anaphase I of meiosis I, the homologous chromosomes get segregated and at telophase I (end of meiosis I) they get divided into two daughter cells, which are known as a dyad of cells (both cells are haploid).

During anaphase II of meiosis II, the sister chromatids get separated and at the end of telophase II (end of meiosis II) four haploid cells are formed.
