Answer:
meiosis you will have four haploid cells (half the number of chromosomes is a diploid cell) and after mitosis you will have two diploid cells
Explanation:
Mitosis you begin with a parent cell that is haploid, it copies all it's chromosomes and splits so each daughter cell have the same number of chromosomes as the parent cell so both being diploid
In meiosis the chromosomes fold over DNA and are put in pairs, in the first division the pairs are split up evenly into two cells randomly (diploid still) but the the cells split the chromosomes in half in them creating four grneticly different haploid cells
