Correct Answer - C
Meiosis - I is called heterotypic division as the two chromatids of a chromosome become genetically different due to the crossing over. Number of chromosomes is reduced to half, hence, called reduction division. Meiosis-II is just like mitosis but occours in haploid nuclei, it is called homotypic or equational division as the chromosomes are distributed equally into daughter cells and chromosome number remains the same in daughter cells.
