(o to som) n. Genetics, any chromosome that is not a sex chromosome (auto - Greek soma body) chromosome (kro mo som), n. any one of the rod-shaped bodies found in the nucleus of a cell that appear when the cell divides. Chromosomes are derived from the parents and carry the genes that determine heredity, controlling the development of the organism and determining its nature. They are of a definite number for each species and occur in pairs in most organisms, except in the germ cells ( (gamete (reproduction cell), egg or sperm cells). The genetic material in each chromosome is a long polynucleotide strand, usually of deoxyribonucleic acid (DNA) but sometimes of ribonucleic acid (RNA), set in a protein matrix. (Note: Mice have an equal chromosome number to man). chromosome number, Biology. the number of chromosomes present in a given species or organism,normally constant for each species: A recount indicates that the human chromosome number ordinarily is 46 (44 autosomes plus 2 sex chromosomes) and not 48 as believed for so long (Lorus and Margery Milne) p. 366, Vol A-K, World Book Dictionary, ed, 1979.

The 22 numbered chromosomes are called autosomes, in contrast to the sex chromosomes.

Any paired chromosome that is alike in the cells of males and females, as distinguished from the sex chromosomes X or Y. Humans have 22 pairs of autosomes.

Any of the chromosomes that are NOT invovled with sex determination. B b

one of the non-sex-determining chromosomes. Autosomes occur in nearly identical pairs. See also and .

All chro mosomes except those involved in sex determination.

one of the non-sex chromosomes; there are 22 pairs of autosomes

a chromosome other than X or Y

a nonsex chromosome

Any human chromosome apart from the sex chromosomes, X and Y. There are 22 pairs of autosomes, numbered 1-22.

Any non-sex-determining chromosome; in humans there are 22 pairs of autosomes. See also: Chromosome See also: DNA

Any of the "numbered" chromosomes -- not the X, Y, or mitochondrial chromosomes. Each human has two copies of each; one inherited from the mother and one from the father. The image below is a schematic drawing of all the human chromosomes (except the mitochondrial chromosome). The autosomes are the chromosomes labeled with numbers. Every cell in the body has two copies of each autosome (with a few exceptions.) The X and Y chromosomes are different from the autosomes because men have one X and one Y chromosome, whereas women have two X chromosomes.

A chromosome other than the sex-chromosome, or sex-deter-mining chromosome.

A chromosome that is not one of the sex chromosomes.

All of the 22 pairs of chromosomes that human cells have, excluding the sex chromosomes (X and Y)

All chromosomes except those involved in sex determination. Humans have 22 pairs of autosomes and the X and Y sex chromosomes (XX for females, XY for males).

The chromosomes of a complement other than those involved in sex determination.

The general name given to all chromosomes other than the two involved in determining the sex of an individual (the X and Y chromosomes). The dog has 38 pairs of autosomes and one pair of sex chromosomes.

Any chromosome that is not a sex chromosome; appear in pairs in body cells but as single chromosomes in spermatozoa.

All of the chromsomes that are not the sex chromosomes.

Any chromosome other than a sex chromosome; humans have 22 pairs of autosomes. [Talking Glossary

one of the first 22 pairs of chromosomes.

Any eukaryotic chromosome not involved in sex determination. Autosomes constitute the vast majority of an organism’s chromosomal complement.

any chromosome not involved in sex determination. Twenty two of the human chromosome pairs are autosomes.

Any chromosome that is not a sex chromosome; in humans there are 22 pairs of autosomes and one pair of sex chromosomes.

A chromosome that is not a sex chromosome. Humans have 22 autosomes, numbered 1 to 22 based on their size.

Any chromosome other than the sex (X or Y) chromosomes.

any of the non-sex chromosomes.

A chromosome not involved in sex determination. The diploid human genome consists of 46 chromosomes, 22 pairs of autosomes, and 1 pair of sex chromosomes (the X and Y chromosomes).

A non-sex-determining chromosome. Cells have 22 pairs of autosomes and a pair of sex-determining chromosomes.

All chromosomes except the X and Y (sex determining) chromosomes. Human cells have 22 pairs of autosomes.

any chromosome that is not involved in determining an organism's sex. Humans have 22 pairs of autosomes in each cell.

A chromosome not involved in sex determination. In a normal human cells there 22 pairs of autosomes. See also: Chromosome. See also: Sex-Chromosome

Any of the numbered chromosomes that are not involved with sex determination.

A chromosome, but not one that is involved in determinating the sex of a human. The human genome consists of 46 chromosomes, 22 of which are pairs of autosomes, and 2 of which are a pair of sex chromosomes (the X and Y chromosomes).

Any chromosome other than a sex chromosome. Humans have 22 pairs of autosomes.[Close Window

Any chromosome except for the sex chromosomes "X" and "Y;" a chromosome not involved in sex determination.

A chromosome other than a sex chromosome.

Any chromosome other than the sex chromosomes X and Y. An autosomal trait is one whose gene(s) is not on the X or Y chromosome and therefore, can be transmitted to either sex.

A chromosome that is not a sex (X or Y) chromosome.

An autosome is a non-sex chromosome. It is an ordinary pairedIn the case of higher ploidy levels than the usual diploid, there will be the same number of an autosome as the ploidy level itself. For example, in a pentaploid, there will be five copies of each autosome., of chromosome that is the same in both sexes of a species.
