a gene found on an AUTOSOME. Autosomal gene. A gene found on one of the 22 autosomal chromosome pairs; i.e., not on a sex (X or Y) chromosome. autosomal gene. a gene located on a chromosome other than the sex chromosomes.
For most autosomes, both the parental and maternal alleles are expressed. However, in 1 % of alleles, expression is possible only from the paternal or maternal allele. For example, expression of the gene for insulin-like growth factor 2 is normally expressed only from the paternal allele. Genomic imprinting is usually determined by effects that occur normally in the development of gametes.
