Are X Chromosome Genes More Mobile Than Others?

NEW YORK, Jan. 23 (GenomeWeb News) - Genes on the X chromosome moved around more during evolution than genes on other chromosomes, researchers reported today.


Scientists from the University of Chicago analyzed a gene export process in humans and mice in which genes are copied in reverse and re-inserted at other locations in the genome. In this week's journal Science, they report that during evolution, genes on the X chromosome underwent this "retrotransposition" more often than genes on other chromosomes. Also, many of the genes that left the X chromosome for a non-sex chromosome are expressed only in males.
