Autosomes all the chromosomes other than the X and Y chromosomes
(auto = self; soma = body)

autosomes The chromosomes other than the sex chromosomes. Each member of an autosome pair (in diploid organisms) is of similar length and in the genes it carries.
5 pairs of autosomes and, usually,
2 X chromosomes.
These animals are hermaphrodites, producing both sperm and eggs.
Most of the time they fertilize themselves, so that any recessive alleles quickly become homozygous and affect the phenotype.
There are 44 autosomes and 2 sex chromosomes in the human genome, for a total of 46. Karyotypes are pictures of homologous chromosomes lined up together during Metaphase I of meiosis.
Genome -- all of the genes carried by a single gamete; the DNA content of an individual, which includes all 44 autosomes, 2 sex chromosomes, and the mitochondrial DNA. Genotype -- genetic constitution of an organism.
Of these, 22 are autosomes and 1 is a sex chromosome.
Clones A group of cells derived from a single ancestor.
Cloning The process of asexually producing a group of cells (clones), all genetically identical, from a single ancestor.
A library prepared from a female donor will contain DNA from the X chromosome in an amount equivalent to the autosomes, but will completely lack Y chromosomal DNA.
In 1959 Susumu Ohno showed that the two X-chromosomes of mammals were different: one appeared like the autosomes; the other was condensed and heterochromatic (Ohno S, Kaplan WD, ...
We actually have a total of 23 pairs of chromosomes in these cells, for a total of 46 chromosomes, but two of those are referred to by letter rather than by number and are called sex chromosomes rather than autosomes, ...
Unlike the twenty-two pairs of autosomes, there is no recombination between the X and most of the Y chromosome.
Mothers give 22 autosomes (1-22) and an X chromosome. Fathers give us 22 autosomes and either and X or a Y chromosome. The father determines the sex of his offspring. If the sperm contains an X chromosome, the baby will be a girl.
The diploid human genome consists of 46 chromosomes, 22 pairs of autosomes, and one pair of sex chromosomes (the X and Y chromosomes).

20 These coiled DNA strands, or chromosomes, can be found in twenty-three pairs-twenty-two autosomes (non-sex determining chromosomes) and one pair of sex chromosomes which determines the sex of the individual.

A human cell contains 23 pairs of homologous chromosomes: 22 of them are homologous non-sex chromosomes (or autosomes) and 1 homologous pair of sex chromosomes. In females, the homologous sex chromosomes are 2 X's; in males the X and Y chromosomes.
Humans have 23 pairs of chromosomes - so 46 in all - 44 autosomes and two sex chromosomes. Each parent contributes one chromosome to each pair, so children get half of their chromosomes from their mothers and half from their fathers.
Humans have 23 pairs of chromosomes (46 total) chromosomes. Two of these are called sex chromosomes, the other 44 are called autosomes.
A term coined by Montgomery (1906) for the chromosome not involved in sex determination; a chromosome other than a sex chromosome. The diploid human genome consists of 46 chromosomes, 22 pairs of autosomes, ...
