46 chromosomes in human's cell. And all these are in form of pairs ,so 23 pairs of chromosomes in human body cell.

I have to correct the first answerer--the "normal" number of 46 chromosomes is the DIPLOID number, not the haploid. In egg and sperm cells, half the number is present, and this is known as the haploid number.

In some individuals, the diploid number is off; this is known as either a monosomy (only one of the usual pair is present), or a trisomy (3 copies, instead of two). The most well-known trisomy is Trisomy 21--3 copies of the 21st pair, otherwise known as Down Syndrome. This is not always obvious simply from counting chromosomes in a karyotype, as the extra material can be attached to another chromosome. Extra/missing X or Y chromosomes are other common genetic mistakes.

There are 22 pairs of autosomes( chromosomes which are responsible for any feature in the body other than sex determination) and 1 pair of allosomes or sex chromosomes( wwhich determines the sex of an individual). Therefore there is a total of 23 pairs of chromosome in a human body cell.

However the human gametes formed by meiosis have haploid number of chromosomes i.e. they have only 23 chromosomes instead of 46; so that after fertilization the zygote has 23 pairs of chromosome(23 from the sperm and 23 from the ovum).

The number of chromatin fibres in our body is 46 but during the time of cell division these fibres become thick and ribbon like. At that these fibres are known as chromosomes and there are 23 pairs of chromosomes present in our body cells.

In case of mitosis the division takes place after duplication of the fibres but in case of meiosis the 46 chromatin are reduced into 23 chromatins and during the time of fusion of the two gametes(egg cell and sperm) the number 46 is maintained.

Meaning, 23 chromatins from the egg cell and 23 from the sperm. after the process of meiosis the process of mitosis is carried out.

Think of chromosomes as chapters of a cookbook. You have a total of 46 but you have 2 copies of each chapter, so 23 pairs:

There are 46 chromosomes (23 pairs) in a human body cell with the exception of the sex cells. One of each pair is inherited from the mother's egg, the other from the father's sperm. When the sperm and egg unite in fertilization, they create a single cell, or zygote, with 46 chromosomes.

When cell division occurs, the 46 chromosomes are duplicated and the process is repeated billions of times over, with each of the cells containing the identical set of chromosomes. Only the gametes, or sex cells, are different. In their cell division, the members of each pair of chromosomes are separated and distributed to different cells. Each gamete has only 23 chromosomes.

Chromosomes contain thousands of genes that have information for a specific trait. That information is in the form of a chemical code, and the chemical compound that codes this genetic information is deoxyribonucleic acid or DNA.

A gene can be seen as a sequence of DNA that is coded for a specific protein. These proteins determine specific physical traits (such as height, body shape, color of hair, eyes and skin), body chemistry (blood type and metabolic functions) and some aspects of behavior and intelligence.

More than 150 human disorders are inherited and genes are thought to determine susceptibility to many diseases.

Somatic cells (body cells) are haploid cells . They have 23 pairs of chromosomes. Reproductive cells (gametes) have half the normal number i.e. 23. This is because two gametes (one male and one female) have to fuse hence, restoring the original number of 23 pairs.

There is 23 pairs of chromosomes. 22 pairs are called autosomes and 23rd pair determines the sex of the individual whether male or female so called sex chromosomes. Male will have XY chromosome and females will have XX chromosome.

Generally X chromosome inherited from the mother to the child and the sex of the child is decided based on the combination of chromosome obtained from the father.

X acts dominant whereas Y as recessive. If there is any alteration in the number of chromosomes the resulting child will have congenital abnormality

Chromosome is a thread like structure of DNA and proteins present in the cell. It is a small piece of DNA containing nucleotides and genes. In our body, there are 22 pairs of autosomes and 1 pair of sex chromosomes for a total of 23 pairs or 46 chromosomes. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

In every cell in the body apart from the sex cells (gametes) there are 23 pairs of chromosomes, 46 all together.

However, sometimes during meiosis a pair of chromosomes doesn't split so the offspring has an extra, or a missing chromosome. In these cases, syndromes like Downs sydrome or Edwards sydrome can occur.

The sex cells (gametes) have 23 chromosomes in them. This is called haploid. You get haploid and diploid. Diploid is when there is the full amount of chromosomes in the cells, and haploid is when there is half. Remember it as HAploid = HAlf.

23 pairs of chromosomes, which results in 46 chromosomes.  22 of the pairs are automsomes, while 1 pair in the sex chromosomes (which XX results in a female and XY results in a male).

I would like to clarify that sometimes people can have more or less than 46 chromosomes is not due to mutation, but rather nondisjunction.  Basically it is caused by improper division of chromosomes during meiosis.  The only time someone can survive from nondisjunction (result in a vilable baby) is when the person has an extra chromosomes 21, or an extra sex chromosomes.  Also one may survive with only 1 X chromosome or missing part of chromosome 5.

Extra chromosome 21:  Down Syndrome

Missing a partial Chromosome 5:  Cri du chat Syndrome (aka Cat's Cry)

XXX:  Tripe X Syndrome 

X: Turner's Syndrome

XYY:  XYY Syndrome 

XXY:  Klinefelter's Syndrome

You guys are all wrong... The question was how many chromosomes are in a human cell, not the human body. If you wanted to know how many chromosomes were in the human body that is correct unless you have some sort of a defect. But each body cell only has 2 chromosomes making it a diploid. Each human gamete cell (Sex cell) has only one chromosome making it a haploid.

 

So to answer your question its 2 chromosomes.

22 pairs are autosomes - related to character and body function 

1 pair of sex chromosomes _ related to the sex of the human involved

There are 46 chromosomes (which can be paired to be 23 pairs) in a body cell.

"22 pairs of autosomes and one pair of sex chromosomes."

There are 46 chromosones all together, but since they come from each parent, there are 23 pairs.

In total, that would be 46 chromosomes in the human body cell. In other words, 23 will come from your mother and the other 23 will come from your father.

  1. In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

The human body cells each contain a total of 46 chromosomes, which are grouped into 23 pairs, one set from each parent.  Each cell receives a chromosome carrying the same traits from both parents, which then forms a pair.  There are 22 pairs of "normal" chromosomes, and 1 pair of sex chromosomes. For the sex chromosomes, an XX means you are a girl, and an XY means you are a boy.  These chromosomes reside in the nucleus of the cell.

In one cell taken from the body, there are 23 pairs of chromosomes that total to 46 chromosomes all together. However, you don't want to assume that all the cells in the human body have 46 chromosomes, because that is not true. Gametes have 23 chromosomes in them, with no pairs.

There are 46 total chromosomes in a normal human body cell. They pair up, creating 23 pairs of chromosomes.

Mutations can occur during cell division, causing human cells to have a varied amount of chromosomes - more or less. There are many genetic diseases caused by chromosomal mutations.

Human sperm and ovum only contain 23 chromosones.  They are formed through meisosi.  All other (normal) cells contain 46 chromosones.  Many cells mutate before full development, however, they do not make changes. For example, a cell on my skin may reproduce and have a severe mutation in my eye color, hair color, or anything.  However, since that particular cell will die off and is only on my skin, it is unlikely it will ever be transmitted to my progeny.
