Thus, the STS locus must have been involved also in the deletion of Xp. Creation Date:. The Editors of Encyclopaedia Britannica Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree This could mean either that the Xg locus is not subject to inactivation or that all Ph-positive cells are not monoclonal.
Also assumed, of course, was that the erythroid cells in the patients studied were derived from a Ph-positive cell and that no red cells derived from Ph-negative precursors persisted. Learn More in these related Britannica articles:.
Assignment by deletion mapping of the steroid sulfatase X-linked ichthyosis locus to Xp Definitive xg-cell surface antigen and x-chromosome sex linked traits in Jacksonville for the short arm of the Y chromosome associating with the X chromosome during miosis in the human male.
The three 5' exons reside in the pseudoautosomal region and the remaining exons within the X-specific end. Genes that share domains with XG: view. Single-copy DNA sequences specific for the human Y chromosome. Lastly, the mating of an Xg a -positive male with a negative female gives the results shown in Figure Related Video.
The patches of fur on a calico cat are orange and black, and the color depends on which X chromosome is inactivated within each patch of color.
In her review, Johnson stated that the XG gene, which encodes Xg a , spans the pseudoautosomal boundary between the 2 regions of the X chromosome at Xp Data on linkage of the Xg locus with many other loci are summarized by Race and Sanger Evidence for lyonization came from a study of X-linked hypochromic anemia by Lee et al.
