Answer:

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.
