Abnormalities in the chromosomes autosomes or sex chromosomes results in the retardation in growth of an organism or delay in development. In autosomes the centromere position is identical. If the duplication or deletion is large enough, it can be discovered by analyzing a karyogram of the individual.
It means they autosomes are responsible for transferring the genetic information from parents to their offspring. Autosomal recessive diseases, however, require two copies of the deleterious allele for the disease to manifest.

Perrin N Sex reversal: a fountain of youth for sex chromosomes? And he had no idea he was even doing it! In humans, there are 46 or 23 pairs of chromosomes, out of which 22 pairs are autosomes, and a pair is the sex chromosomes or allosomes. Chromosoma 65 1 — Cytogenet Genome Res 1 — There is a total of 46 chromosomes in the human genome.
Heteromorphic sex chromosomes are common in eukaryotes and largely ubiquitous in birds and mammals.
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.

Human genome. 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 determine what sex, or gender, we are.
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. These are also known as allosomes.

This article explains. tions between sex chromosomes and autosomes. In this chapter, we will provide an overview of this emerging area of genome evolution, often rapid in nature, which has been driven by evolutionary interactions between the sex chromosomes and the autosomes.

autosomes or Y chromosome (Dobzhansky ; Moran ; Coyne , a; Coyne and Kreitman ; Naveira and Fontdevila ) and between the Y chromosome and the autosomes (Zouros b; Vigneault and Zouros ) as * Present address: Department of Biology, University of Chicago, East 57th Street, Chicago, Illinois Am. Nat. We develop models of the rates of evolution at sex-linked and autosomal loci and of the rates of fixation of chromosomal rearrangements involving sex chromosomes and autosomes. We show that the substitution of selectively favorable mutations often proceeds more rapidly for X- or Y-linked loci than for the autosomes, provided that mutations are.
