Mitosis-the chromosomes are duplicated and then divide in two. So you have two copies of the original chromosomes, and two cells.
In reproductive cells, the chromosomes replicate and divide twice and then split off so you have one 46-chromosome cell end up as 4 23-chromosome cells.
In sperm you start with one somatic cell (46) and end with four sperm(23-chromosome each).
In eggs you end up with one 23-chromosome egg and three polar bodies.
Meiosis-the chromosomes divide and you end up with 1/2 as many chromosomes as you had in the original cell. Two sets of chromosomes is called diploid. One set is called haploid (23 in humans) as in reproductive cells.
Every somatic cell has the full set of 46 chromosomes needed to make a carbon copy of you.
