  • A sex chromosome , also referred to as an allosome , heterotypical chromosome , or heterochromosome , [1] [2] or idiochromosome [3] is a chromosome that differs from an ordinary autosome in form, size, and behavior. The human sex chromosomes, a typical pair of mammal allosomes, determine the sex of an individual created in sexual reproduction.
  • The key difference between autosomes and sex chromosomes is that the autosomes contain genes that are responsible for the determination of somatic characteristics while the sex chromosomes contain genes that determine sex and sex-related characteristics of an organism. The most important structures in a cell during the cell division are the chromosomes, which contain DNA.
