Does ploidy reduction occur in mitosis, Biology

Assignment Help:

During which meiosis division does ploidy reduction occur? Does ploidy reduction occur in mitosis?

In the cell division by meiosis ploidy reduction occurs in meiosis II. Initially, taking as example a 2n somatic cell, ploidy increases to 4n (duplication of DNA) during interphase. During meiosis I, since homologous chromosomes are separated, ploidy falls to 2n (the original number) and then during meiosis II ploidy finally falls to n in the resulting daughter cells.
