two Barr bodies
A Barr body is the inactivated X chromosome when in a case like this, there is more than one X chromosome for only one place. In this case, because there are two more X chromosomes than it would be normal, it will result in two Barr bodies. So, the number of Barr bodies will be <span>is always the total number of X chromosomes minus one.</span>
