No gametes or sex cells each have 23 chromosomes. Meaning that a sperm would have 23 chromosomes (not pairs) and an egg would have 23 (also not pairs), which are called haploid cells. So when united, they pair and have 23 pairs of chromosomes, or 46 chromosomes.
All human cells contain 46 chromosomes except for the sperm and egg cells which contain 23 each.
A horse has 64 chromosomes arranged as 32 pairs.
Chromosomes are not reproductive cells. They are structures within cells that carry genetic information in the form of DNA. Reproductive cells, like eggs and sperm, contain half the number of chromosomes as other cells in the body.
Sex cells (better known as gametes) being product of meiosis have single set (haploid number) of chromosomes whereas body cells have diploid number. Thus, 22 pairs of autosomes and one pair of sex chromosomes (XY), thus 46 chromosomes are present in our body cells. The gametes (sex cells) contain only 23 chromosomes in each.
There are 46 chromosomes in kidney cells, big toe cells, and tip-of-the-nose cells.This is because humans are diploid organisms (having two sets of chromosomes in all cells except gametes(23 chromosomes) and mature red blood cells, which extruded their nuclei when they were developing), and 46 is the human diploid number.

Yes, chromosomes (the DNA) contain the genetic blueprints for all cells.
In terms of chromosomal number, there are two types of cells in the human body.Autosomes, or body cells, have 46 chromosomes (the diploid number)Allosomes, or sex chromosomes, have 23 chromosomes (the haploid number)
All of them (in humans), apart from sperm and egg cells (which contain 23)
All human cells contain 46 chromosomes except for the sperm and egg cells which contain 23 each.
Gametes Have 23 Single Chromosomes, this means at fertilisation the pairs join together to make 23 pairs of Chromosomes. This is because Gametes are unspecialised cells so don't need all the Chromosomes that specialised cells have.
Yes. In an individual, almost all cells contain DNA (Red Blood Cells do not). That DNA is tightly wound like you would twist a drawstring, and kept tightly coiled as chromosomes. Since chromosomes can be found in a cheek cell, a liver cell (hepatocyte), and almost all other cells, they all contain the same chromosomes, which inevitably have the same genes. What makes cheek cells different from liver cells is which genes are turned on and off. Cheek cells have different genes turned on compared to liver cells.
No, chromosomes are present in almost all cells of an organism. However, they are most readily observed in egg and sperm cells during sexual reproduction because they contain a single set of chromosomes.
A horse has 64 chromosomes arranged as 32 pairs.
All body cells contain a total number of 46 chromosomes except sex cells (the egg and the sperm) which have half the number of chromosomes (23) no.... body cells or somatic cells have 46 chromosomes which is the diploid chromosome number of homo sapiens... gametes or sex cells have 23 chromosomes which is the haploid chromosome number...
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
The only haploid cells found in humans are the gametes, which are the sperm in males and the eggs in females. These cells contain half the usual number of chromosomes (23 in humans) and are produced through meiosis in the reproductive organs.
