Even a small deletion or addition of autosomal material—too small to be seen by normal karyotyping methods—can produce serious malformations and intellectual disability.

Allosomes are the chromosomes that differ from ordinary chromosomes autosomes by size, form, shape, function and behaviour. Stevens and the Discovery of Sex Determination by Chromosomes".

  • Sex chromosome , either of a pair of chromosomes that determine whether an individual is male or female. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y.
  • Autosome , any of the numbered or nonsex chromosomes of an organism. Humans have 22 sets of autosomes; they are referred to numerically e.
  • The key difference between autosomes and allosomes is that the autosomes are somatic chromosomes that involve in determining the somatic characteristics other than sex determination while the allosomes are the sex chromosomes that determine the sex and sex-related characteristics of an organism. Chromosomes are a thread like structures made from nucleic acids and proteins.

Autosomes are known to transfer the somatic characters to the next generation of the same species, while sex chromosomes decide the sex or gender of the upcoming generation. If the duplication or deletion is large enough, it can be discovered by analyzing a karyogram of the individual.

This article explains. An autosome is one of the 22 numbered pairs of chromosomes that most of us carry in almost all of the cells of our body. We actually have a total of 23 pairs of chromosomes in these cells, for a total of 46 chromosomes, but two of those are referred to by letter rather than by number and are called sex chromosomes rather than autosomes, since they--that is the X and Y chromosome--help.

  • Autosomes. Autosomes are chromosomes apart from the sex chromosomes in a eukaryotic cell. In humans, the X and Y chromosomes are the sex chromosomes. All the chromosomes other than the sex chromosomes are autosomes. There are 22 homologous pairs of autosomes in humans. Each autosome has several genes each of which performs certain unique functions. Autosome, any of the numbered or nonsex chromosomes of an organism. Humans have 22 sets of autosomes; they are referred to numerically (e.g., chromosome 1, chromosome 2) according to a traditional sort order based on size, shape, and other properties. Autosomes differ from sex chromosomes, which make up the 23rd pair of chromosomes in all normal human cells and come in .
