Mitotic Cell Division occurs in both haploid and diploid cells
Diploid and haploid cells do not have alternation of generations; this phenomenon occurs in multicellular organisms with a life cycle that alternates between haploid and diploid stages. Mutations can occur in both diploid and haploid cells, but they are more likely to have an impact in diploid cells due to their higher genetic complexity.
A diploid refers to a cell or organism that contains two sets of chromosomes, one set inherited from each parent. Diploid organisms can be found across various species, including humans, animals, and plants. In humans, diploid cells are found in most tissues of the body, except for the reproductive cells (sperm and egg) which are haploid.
Meiosis occurs in the germ cells of the ovaries and testes of the fruit fly during the process of gametogenesis. This is where diploid germ cells undergo two rounds of cell division to produce haploid eggs or sperm.
Haploid cells have a crucial role in sexual reproduction as they contain half the number of chromosomes, enabling fusion with another haploid cell to form a diploid zygote. This process ensures genetic diversity in offspring by mixing genetic material from two parents. Additionally, haploid cells undergo meiosis to generate gametes, such as sperm and egg cells, which are essential for sexual reproduction to occur.
Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)

First off, your query should be "Do mitosis and meiosis produce diploid cells?" The answer is that mitosis produces diploid cells, since mitosis is used to replace body cells, but meiosis produces haploid cells, since meiosis is used to produce sex cells. The sex cells are haploid because a sex cell eventually combines with another sex cell to create a new organism.
Yes, mitosis can occur in a cell of any ploidy. There will only be two daughter cells at the end of mitosis and both cells will have the same ploidy as the parent cell. (e.g. A diploid cell will go through mitosis producing 2 diploid daughter cells. A haploid cell will produce 2 haploid daughter cells at the end of mitosis.)
A diploid refers to a cell or organism that contains two sets of chromosomes, one set inherited from each parent. Diploid organisms can be found across various species, including humans, animals, and plants. In humans, diploid cells are found in most tissues of the body, except for the reproductive cells (sperm and egg) which are haploid.
To achieve a diploid state, the sperm cell must fuse with a haploid egg cell during fertilization. This fusion combines the genetic material from the sperm (haploid) and the egg (haploid) to form a diploid zygote.
During mitosis, diploid cells divide to form two identical diploid daughter cells. Haploid cells do not result from mitosis, as it is a process that preserves the diploid number of chromosomes in daughter cells.
Put simply you can't get a "normal" haploid number from this cell. Normal cells have even diploid numbers so that meiotic division can occur to produce a haploid one with half the number. This cell would encounter problems during meiotic crossing over, and would result in daughter cells with a "mish-mash" whereby the haploid number could be a number of things. Thus fertilisation could not occur normally and the cell would produce infertile gametes. Mitosis could occur normally however so the cell can nultiply asexually. This is effectively what happens with ployploidy ( look it up on wikipedia).
in meiosis, two new haploid sex cells are "born" by the division of two other haploid sex cells. So, at the end, there are 4 nuclei.
Meosis is a process of cell division where a diplod cell becomes four haploid cells resembling mitosis but the chromosomes are duplicated once in which gametocytes form gametes.They occur in genetic information in variation of female and male gametes. In mitosis the nuclei of the diplod cells reproduce after chromosomes duplicate in four stages with two diploid cells formed with identical set of chromosomes with the cytoplasm also divides with the cells. They occur in somatic cells.
A sex cell that has only half ("ha" = half) one set of chromosomes. Once this cell were to join with the other haploid cell (either an egg or sperm, dependant on what the original haploid cell was) and fertilisation was to occur it would then become a diploid cell ("d" = double)

four haploid cells.
