WebAn autosome is any chromosome that is not a sex chromosome. [1] The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosomal ( sex chromosome) pairs, which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA. [2] WebTo be exact, the two copies of a gene carried by an organism (such as a Y and a y allele) are located at the same spot on the two chromosomes of a homologous pair. Homologous chromosomes are similar but non-identical, and an organism gets one member of the pair from each of its two parents.
