The body cells of most humans have 46 chromosomes, which can be arranged into 23 pairs. One chromosome in each pair comes from the mother and the other chromosome comes from the father. Of the 23 pairs, 22 pairs (the body chromosomes, or autosomes) are the same in males and females. The 23 rd pair, called the sex chromosomes, is different in males and females. In females, the sex chromosomes are the same and are called X chrosomes. In males, the sex chromosomes are different. One is an X chromosome (inherited from your mother or your father) and the other is a smaller chromosome called the Y chromosome (inherited from your father). So, the two chromosomes which are found in human males (but not human females) are the sex chromosomes, X and Y. See: http://Biology.about.com/library/weekly/aa091103a.htm

How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
How many chromosomes are in human kidney cells?
Human kidney cells are body cells, so they would have 46 chromosomes.
How many chromosomes does a body cell have?
Human body cells have 46 chromosomes.
How are chromosomes and genes are related?
they have cells and the cells can be in a animal body or it can be in a human body.
How many pairs of chromosomes do each human skin cell have?
Each human cell has 23 pairs of chromosomes or 46 chromosomes.
How many pairs of homologous chromosomes are found in human body cells?
Human cells have 23 homologous pairs. They also must go through meiosis before that. Females have 2 X chromosomes, while Males have an X and a Y chromosome. That's why the males cells decide the gender of the child.
What is the number of chromosomes found in cells?
There are 46 chromosomes in a human body cell.
Number of chromosomes in human body cells?
46 chromosomes 23 pairs
Why is it important to have half as many chromosomes as normal body cells?
The gametes must have half as many chromosomes as normal body cells because they unite to form a zygote, which is the first body cell of the new organism. For example, human body cells have 46 chromosomes and human gametes (sperm and egg cells) have 23 chromosomes. When the sperm fertilizes the egg, the zygote will have 46 chromosomes, and is the first body cell of the new human.
How many chromosomes does a kidney cell have?
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.
How many chromosomes are usually found in human cells?
A single human cell contains 23 pairs of chromosomes (22 autosomes and a pair of sex chromosomes ). These are found in all human cells (RBC's and platelets being exception ). So with human body made up of unbountable number of cells, the actual number of chromosomes in the human body is unbountable times 46= unbountable.
What is number of pairsof chromosomes in the human body cells?
23 pairs, 46 chromosomes
