any of the 22 pairs of chromosomes in humans other than the pair concerned with determination of sex.

(aw'tō-sōm),
Any chromosome other than a sex chromosome; autosomes normally occur in pairs in somatic cells and singly in gametes.
Synonym(s): euchromosome

autosome

(ô′tə-sōm′)
n.
A chromosome that is not a sex chromosome.

au′to·so′mal (-sō′məl) adj.
au′to·so′mal·ly adv.

autosome

A non-sex (non-X, non-Y) chromosome which in normal humans is one of 22 pairs of chromosomes.

autosome

Cytogenetics Any chromosome in an organism's complement–22 pairs in humans–other than sex chromosomes, X and Y See Chromosome, Diploid, Genome. Cf Sex chromosome.

au·to·some

(aw'tō-sōm)
Any chromosome other than a sex chromosome; autosomes normally occur in pairs in somatic cells and singly in gametes.
[auto- + G. sōma, body]

autosome

Any one of the ordinary paired CHROMOSOMES other than the sex chromosomes.

autosome

a type of chromosome found in all cells not concerned with SEX DETERMINATION. Chromosomes are of two types: autosomes and SEX CHROMOSOMES. Autosomes carry the major part of genetic information in cells, including information on sexual characteristics. See SEX LINKAGE for a comparison of the inheritance of autosomal and sex-linked genes.

Autosome

A chromosome not involved in sex determination.

In this species, double-FISH with telomeric and mysTR sequences as probes revealed a few colocalizations in some autosomes and in the transition between the euchromatic and heterochromatic portions of the Y chromosome (Figure 5), although there is no sequence similarity between mysTR and the telomeric [(TTAGGG).sub.n].
For CHO, the threshold LOD scores for significant and suggestive QTL were 3.4 and 2.1, respectively, for autosomes and 2.8 and 1.5, respectively, for Chr X.
Putative paralog motifs were filtered for this application such that 1 target paralog is mapped to a chromosome of interest (chromosomes 18 or 21) and a paired paralog sequence is mapped to an alternative autosome. A proof of concept study, including both chromosome 18 and chromosome 21 fetal trisomies, was completed and compared to genome-wide NIPT results from the MaterniT21[R] PLUS assay.
Savic & Soldatovic (1979b) assumed that the evolution of karyotypes of the Balkan Spalacinae was driven by Robertsonian re-arrangements and most probably took the form of a decrease in the number of acrocentric autosomes and consequently of the diploid number of chromosomes.
Table 1 shows the distribution of the numbers and mean number of Q-HRs on autosomes in alcoholics and drug addicts, as well as in the control groups (residents of Bishkek).
The phylogenetic pattern indicates two independent fusions of a cryptic Y chromosome with an autosome, producing neo-Y chromosomes.
Note that Y chromosomes and mtDNA will show smaller Ne than autosomes because they are haploid (one copy per individual).
Karyotyping of mouse chromosome revealed that chromosome number in mice is 40 (19 autosomes and X and Y sex chromosome).
The overwhelming majority of hypoploid cells characterized with a loss of autosomes of smaller groups.
The other biarmed and acrocentric autosomes were arranged according to their size, respectively.
A chromosome portrait involves probing autosomes (chromosome pairs excluding the sex chromosomes) for specific genes with single nucleotide polymorphisms that correspond to one of "three continental origins" (Asia, Africa and Europe).
