Women born with an extra x chromosome (xxx) are generally healthy and indistinguishable in appearance from normal xx women. what is a likely explanation for this finding? how could you test this explanation?

In this case, if two of the x chromosomes were not activated in women with xxx, it would leave them with a single genetically active x, the same as in women who have the normal number of chromosomes. In order to test this, one should use microscopy to see two Barr bodies that can be found in XXX women.
