Hi and thank you for the question. Any daughter from this couple will always inherit the X chromosome with the genetic variant for the condition from her father, but she may or may not inherit the X chromosome with the genetic variant for the condition from her mother. From this couple: - for daughters, 50% will have the condition while 50% will be carriers for the condition (on average). - for sons, 50% will have the condition and 50% will not have the condition (on average).

What if the father has the condition and the mother is a carrier of the trait, can their daughter have the condition?
