Autosomes differ from allosomes because autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cellwhereas members of an allosome pair may differ from one another and thereby determine sex. However, the researchers used computer simulations to show that the known small size of Neanderthal populations may have led to an accumulation of deleterious mutations in their Y chromosomes which would reduce their evolutionary fitness.
