Yes they do. In humans, sperm and egg cells will contain 23 chromosomes. When a sperm and egg fuse to form a zygote, the diploid number of chromosomes is restored (46 or 23 pairs).
yes
Fertilization.
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
The cell that fertilises the egg cell is called the sperm cell. _-------O That's how a sperm cell looks like <<<<<<<<<<<<<<<<<

If you're talking about a human cell, then no. Diploid means you have two complete sets of chromosome. For a human, this would be 46. A human cell is haploid when it has only 23 chromosomes - this is the case for the sex cells: sperm and egg each have 23 chromosomes.The issue can be confused if you discuss chromosome pairs...in which case, 23 pairs of chromosomes in a human cell makes it a diploid cell.
If the diploid (2N) number is 64 the haploid (1N) number is 32.
monoploid, monoploid and diploid
FERTILIZATION
If the somatic (normal) cell has 38 chromosomes, then the diploid number will be 38. If the gametes (sperm and ovum/egg) have 38 chromosomes, then the diploid number will be 76.
A cellwith two of each kind of chromosomeis called a diploid cell and is said to contain a diploid, or 2n, number of chromosomes.
There are 22 in each, along with an X sex chromosome for the female form and a Y sex chromosome for the male form.
A cell that has two copies of each chromosome, one from an egg and one from a sperm.
Diploid I think
Fertilization.
are little more than flagellated nuclei. Each consists of a head, which has an acrosome at its tip and contains a haploid set of chromosomes in a compact, inactive, state.
In most plants and animals, each cell has two copies of each chromosome. Cells having 2 of each kind of chromosome are called diploid. For instance, human cells have 46 chromosomes (23 different kinds of chromosomes, and 2 copies of each kind). They are diploid. Now think about what happens when a sperm fertilizes an egg. If a sperm has 46 chromosomes, and an egg has 46 chromosomes, then you might think that the fertilized egg would have 92 chromosomes since it is formed by putting together the sperm and the egg. But this doesn't happen. Why not?Sperm cells and egg cells are produced by a process of cell division called meiosis that cuts the number of chromosomes in half (each sperm cell has 23 chromosomes and each egg cell has 23 chromosomes). Then when the sperm and egg combine during fertilization, they produce a cell that has the normal number of chromosomes again. (23 + 23 = 46). Meiosis reduces the number of chromosomes by putting one of each kind instead of two of each kind in each sperm and in each egg. Cells that have only one copy of each kind of chromosome are called haploid. Sperm cells and egg cells are haploid. All other cells in the body have two of each kind of chromosome and are called diploid.
50 % of human sperm Cells are an X chromosome, the other half are a Y chromosome: {diploid = 2n = 1 chromosome pair; haploid = n = 1 chromosome - including the meiotic single chromosome = n}. All sperm and egg Cells carry one set each of n (23 single) chromosomes. When a sperm and an egg combine either: a) a sperm Cell with the X chromosome merges with the [X-chromosome] egg Cell and the baby will be a girl; or b) a sperm Cell with the Y chromosome merges with the egg Cell and the baby will be a boy.
