The sex chromosomes in bryophetes affect what type of gamete is produced by the gametophyte, and there is wide diversity in gametophyte type.

About to number of different genes are present in autosomes, and the chromosome 1 in humans which is known to be the largest contains approximately genes; in contrast, the X sex chromosome consists of more than types of genes, and y sex chromosome consists of merely a few examples of genes because it is relatively small in size.

  • 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 main difference between Autosomes and Sex Chromosomes is that Autosomes are usually taken part in defining the somatic types of an organism, whereas, Sex Chromosomes are generally taken part in establishing the sex of an individual and sex-linked hormonal characters. Autosomes usually determine the characters of an individual, and all males and females consist of some type of autosomes; on the other hand, sex chromosomes typically determine the gender of an individual, and all males and females contain different sex chromosomes according to their form, size, and behavior.

Although traditionally attributed to gonadal sex hormone effects, recent work has begun to shed more light on the contribution of genetics — and in particular the sex chromosomes — to these sexual dimorphisms.
