Sex chromosomes and the evolution of sexual dimorphism: lessons from the genome. Genic mutation rates in mammals: local similarity, chromosomal heterogeneity, and X-versus-autosome disparity. PLoS Biol 8 : e Supplementary Information accompanies this paper on Heredity website.
The Drosophila X does not just have fewer than expected male-biased genes; it also is particularly depauperate for genes that are the most highly expressed in testes. Unfortunately, a comprehensive understanding of the historical demographic history of C.

It proves the Mendelian inheritance. The autosomes are recognized as chromosomes which are other than the sex chromosomes, and usually define the attribute of an individual. There are many genetic disorders which can happen if something goes wrong with these chromosomes. The conducting of DNA research has made it possible for me to be part of something new.
The application of genomic methods here has allowed us to better define patterns of genetic variation in sage-grouse and also begin to understand the mechanisms underlying speciation in these species. The tan cylinder is the histone octamer, the blue rope is the DNA, and the H1 domain that interacts with the nucleosome is in yellow.
If we can confirm that the presence of heteromorphic sex chromosomes accelerates speciation via increasing the rate at which hybrid incompatibility evolves, species selection would be acting on the species-level trait heteromorphic sex chromosomes. The biochemical mechanisms of Drosophila dosage compensation have been worked out.
