Human male XY chromosomes after A<unk>  (also referred to as an allosome, heterotypical chromosome, gonosome, heterochromosome, or idiochromosome) is a chromosome that differs from an ordinary autosome in form, size, and behavior. The human<unk> s, a typical pair of mammal allosomes, determine the<unk>  of an individual created in<unk> ual reproduction. Autosomes differ from allosomes because autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell, whereas members of an allosome pair may differ from one another and thereby determine<unk> . Nettie Stevens and Edmund Beecher Wilson both independently discovered<unk> s in 1905. However, Stevens is credited for discovering them earlier than Wilson.
