The genome-wide association tests were carried out mainly on 38 autosomes with the Sap183 data set, because of its greater sample size compared to the Sap60 and Sap134.
Furthermore, no statistically significant association of arsenic exposure was observed in relation to global methylation levels across autosomes on a genomic scale.

Karyotyping of mouse chromosome revealed that chromosome number in mice is 40 (19 autosomes and X and Y sex chromosome).
The percentages of reads mapped to individual autosomes compared to total reads mapped to all autosomes were calculated.
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).
Chromosomal breaks and/or gaps affecting autosomes and sex chromosomes were seen in 5 of a total of 14 cases.
The overall frequency of trisomy was likely even higher than we observed in our series (10 of 102 or approximately 10%), since the Identifiler STR panel covers only 14 of the 22 autosomes and does not include markers on some of the chromosomes frequently implicated in autosomal trisomy (eg, chromosomes 15 and 22).
26) In twenty-two of these pairs, called autosomes, the two chromosomes are about the same length.
Of these, 44 are known as autosomes and consist of matched pairs of chromosomes, known as homologous chromosomes.
The only three that have been associated with viability after birth are trisomies 21, 18, and 13, and these chromosomes are the autosomes with the least number of genes per chromosome.
These comprise 22 pairs of autosomes and one pair of sex chromosomes which looks like two wires twisted around one another.
