X - LINKED CO-DOMINANT

X-linked co-dominant

• In female cells, one or the other X chromosome must be inactivated. This occurs more or less at random.
• Female mammal has patches of cells with one X chromosome inactivated, and patches with the other X chromosome inactivated.
• If the gene is expressed directly within the cell, the mosaic nature of the female may become obvious.
  • Example : Tortoiseshell cat
