Which type (s) of cell division (mitosis, meiosis l, meiosis Il) reduce (s) the chromosome number by half? Which type (s) of cell division can be classified as reductional? Which type (s) of cell division can be classified as equational?

Which type (s) of cell division reduce (s) the chromosome number by half?

Meiosis l

Which type (s) of cell division can be classified as reductional?

Meiosis I

Which type (s) of cell division can be classified as equational?

Mitosis and Meiosis II

Explanation:

Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II. The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.

Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.
