Lets say that the genotypes are:
Male affected:XbY
Male unaffected: XaY
Female  affected: XbXb
Female carrier: XaXb
Female unaffected:XaXa
P: XbY  x  XaXa
F1: XaXb  XaXb  XaY  XaY The middle square is female carrier.
P:XbY  x  XaXb
F1: XaXb  XbXb  XaY  XbY The left square is affected female.
P:XaY  x  XbXb
F1: XaXb  XaXb  XbY  XbY The right square is affected male.
