Evolution of the Y Sex Chromosome in AnimalsY chromosomes
... Males ha ve an X and a Y sex chromosome (XY), whereas females have two X chromosomes (XX). In most respects the human X is organized genetically like an autosome. Its major distinction is that it undergoes dosage compensation, a phenomenon whereby, in females, most genes on one of the X chromosomes ...

The evolution of genomic imprinting and X
... Another similarity between the PWS-AS domain and the XIC is that both their evolutionary histories were demarcated by genomic rearrangement. I discovered that the protein coding genes in the region homologous to the XIC of marsupials and monotremes independently underwent fission (Figures 3.3 and 3. ...
