Diploid,eukaryotic cells undergo meiosis.Four haploid cells are prodced.Diploid cells are made after fertilization.

yes its how they reproduceBacteria do not have nucleus. So they cannot reproduce sexually. Just multiplication of cells occur
Many organisms use mitosis and meiosis. Namely, all eukaryotes probably use mitosis and meiosis. Only bacteria (prokaryotes) would not divide by mitosis and have no mechanism for meiosis as their chromosomes differ from those of eukaryotes.But eukaryotes all have the capacity for mitosis and meiosis. Eukaryotes include all animals, plants, protists and fungi.Thus, since pigs are animals (and are thus eukaryotes), then indeed they have cells that divide by mitosis and meiosis. Their body cells (somatic cells) divide by mitosis (for growth and repair). Their gametes (sperm cells and ova) are produced by meiosis as these cells must be divided to a haploid form before copulation and fertilisation. Two haploid gametes would fuse (fertilisation) to restore the resulting cell (zygote) to a diploid form. The zygote grows into a new piglet via mitosis.
Meiosis
Germ cells use a similar, but not identical, process to divide known as meiosis. Many adult cells do not divide at all under normal conditions, such as neurons and red blood cells.
Any kind of animal that is asexual uses meiosis for reproduction. Examples of these are sea sponges, star fish, protozoa, and many more animals.
Hermit crabs use meiosis to reproduce
all cells except for gametes.
Two types of cell division in eukaryotes (nucleated organisms) are meiosis and mitosis. Meiosis halves the number of chromosomes and produces gametes. Mitosis retains the number of chromosomes and is involved in growth and repair of injury.
All human cells have 46 chromosomes, 23 pairs. In sexual reproduction, if an egg and a sperm each with 46 chromosomes joined then the zygote would have 92 chromosomes. To keep this from happening, cells undergo meiosis. In meiosis the cells replicate the chromosomes and divide then divide again so they end up with only 23 chromosomes. Cells with half the number of chromosomes are called gametes.
Mitosis is the form of cell division that most eukaryotic cells undergo. In humans, all somatic (non-sex) cells use mitosis to divide. Sex-cells use meiosis instead of mitosis.
