A diploid cell. In other words, a cell containing 2n chromosomes.

They must reduce their number of chromosomes by half so that way when they do fuse, the two halves of genetic material equal a full cell.
Meiosis results in cells with 23 chromosomes because it involves two rounds of cell division. During the first division, the chromosome number is halved from the original 46 to 23, ensuring that when the cells fuse during fertilization, the resulting offspring maintains the correct number of chromosomes. This reduction in chromosome number helps to create genetic diversity in offspring.
I am not sure what your saying, but i think you mean "what are the haploid cells involved in fertilization?" In this case the answer would be " sperm and egg cells", which then makes a diploid.
depends on the organism, but (i think) it should be half the normal number of chromosomes in a normal cell, because the gametes (egg and sperm) are haploid cells, meaning they have half the number because when they fuse together in fertilisation they need to have the correct amount of chromosomes so that they can duplicate and grow into an embryo.
During meiosis, a cell with half the normal number of chromosomes (haploid) is generated to eventually form gametes (sperm or egg). When two haploid gametes fuse during fertilization, they restore the full set of chromosomes (diploid) in the zygote. This zygote then undergoes mitotic cell divisions to produce cells with the normal number of chromosomes.
In a normal Human body cell (not a gamete) there are 46 chromosomes. This is not the same number of chromosomes in our bodies, only in one cell, and there are trillions of cells in the human body. In a gamete (a sperm cell or egg cell) there are 23 chromosomes. When the sperm and egg cell nuclei fuse in fertilisation, a diploid cell of 46 chromosomes is produced.
No, sex cells contain half the number of chromosomes that somatic (non-sex) cells contain. They are therefore haploidcells.
A human egg/sperm cell has 23 chromosomes. When the sperm and egg fuse together,, the zygote (fertilised egg) contains 46 chromosomes. Scientists call this the diploid number, with the sperm/egg having a haploid number of chromosomes. This number varies between species.
A sperm cell from the same species would also contain 50 chromosomes. When an egg and sperm fuse during fertilization, the total number of chromosomes in the resulting zygote will be the sum of the chromosomes from the egg and sperm, which would be 100 in this case.
In the sex cells you only have half of the number of chromosomes- 23 instead of 46 which is what you have in your other body cells This is because when the sperm fertilizes the egg, the two nuclei fuse together and the chromosomes combine so you then have the right number for normal body cells to develop in the baby.
There are 23 chromosomes in each the sperm and the egg. When they fuse, the resulting embryo will have 46 chromosomes.
