Apparently in this case the evolution of repeated sequences has played a major role in incompatibilities, which could help to maintain reproductive isolation between species
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.
An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes.

During the cell division, chromatin in the nucleus shrinks to a thread like structures named chromosomes.

Apr 25, · AlphaImpute is a flexible and accurate genotype imputation tool that was originally designed for the imputation of genotypes on autosomal chromosomes. In some species, sex chromosomes comprise a large portion of the genome.
