I spoke with T. Krahn about X-Testing-Answer

Men get 1 X gene from their mother so when they pass the X down a daughter it has no chance to recombine with another X because he has XY.

All females from the same father will share the same X.

A woman who has 2 X one from mother and one from father. When she passes her X down to her children they will recombine so each sibling will recieve a different X from their mother.

He said it is very rare, he gave me 3% chance, that a woman's 2 X will not recombine and she will pass the same X to her children.
