There are only two variations of the sex chromosomes X and Y. A typical female has XX, while a typical male has XY. There are a few conditions where other combinations are present such as XO (a single X), XXX, XYY etc, but they are all combinations of X's and Y's.
The human sperm cell has 23 chromosomes. White blood cells have 46 chromosomes. Mature red blood cells to not contain a nucleus, and therefore has no chromosomes. Platelets are cell fragments and also do not contain nuclei.
chromosomes contain mitochondria, which acts just like a battery.
Human muscle cells contain 23 pairs of chromosomes.
There are 46 chromosomes. They are in 23 pairs

A sex cell contains half the number of chromosomes found in a somatic (normal) cell. Therefore a human sex cell would contain 23 chromosomes.
46 chromosomes. The only cells in the human body that do not contain 46 chromosomes are specialist cells which have no cell nucleus (eg a human red blood cell) and reproductive cells, which only contain 23 chromosomes. Thus the cheek cell of the animal would be no different from any other cell in its number of chromosomes and would contain the full number of chromosomes for that animal.
Humans have 46 chromosomes. This means they will produce sex-cells (sperm and ovum/egg) which have 23 chromosomes.
Normal human diploid cells contain 46 chromosomes.
A sex cell contains half the number of chromosomes found in a somatic (normal) cell. Therefore a human sex cell would contain 23 chromosomes.
Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
All human cells contain 46 chromosomes except for the sperm and egg cells which contain 23 each.
