A somatic cell with two of each type of chromosome has a diploid chromosome number. This means that the cell has a complete set of chromosomes, one from each parent.
The diploid number of chromosomes in a horse's cell is 64, therefore they have 32 pairs of chromosomes in their somatic cells.

They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
Its haploid number, which will be half the number of chromosomes found in somatic (non-sex) cells - the diploid number.
Yes, In most cases all somatic cells are diploid but in some organisms it is not the case, Gametophytes of plants are always haploid. Bacteria are also haploid. In angiosperms, the endosperm; which is considered somatic; is a tissue consisting triploid cell. Some time its chromosome number varies from 2n to 15n.In some conifers , like Sequoia sempervirens, chromosome number is 6n (Hexaploids).So, even in somatic cells, there is a large variety in chromosome number.
A haploid germ cell has the same number of chromosome sets as a gamete, which is half the number of chromosome sets found in a somatic cell. This enables the gametes to fuse during fertilization to restore the diploid number of chromosomes in the zygote.
Anaphase is the stage of cell division where the chromosomes are pulled apart to opposite ends of the cell. During anaphase, each chromosome consists of two chromatids, so the number of cells remains the same as in earlier stages of cell division.
In plants, the gametes (such as pollen and egg cells) have half the number of chromosomes as somatic cells. This means that the pairs of cells that do not have identical chromosome numbers in a plant species are the gametes and somatic cells. Gametes have half the number of chromosomes as somatic cells due to the process of meiosis that reduces the chromosome number by half during gamete formation.
It depends on whether you're talking about mitosis or meiosis. In mitosis, it is during anaphase. In meiosis, where the cell divides twice, centromeres aren't separated until anaphase II. In anaphase I, chromosomes are arranged as tetrads, and these tetrads are pulled apart to create two daughter cells, each with a full copy of the original cells' diploid chromosome.
