In X-linked recessive diseases, why are females who inherit only 1 disease-causing allele carriers, since 1 of the 2 chromosomes is inactivated? What if the chromosome with the normal allele is the one that is inactivated, and the other disease-causing allele is the active one? Why isn’t X-inactivation taken into consideration? Why are females always carriers, and not affected by chance depending on which X chromosome is inactivated?

I'm doing research for a book and I have a question regarding sex and gender. One of the biggest issues facing the LGBTQ today is transgender discrimination. Many people of course are arguing there are only just two genders (i.e. sexes) male and female. But in doing research, there seem to be more combinations at least at the DNA level. Instead of just XX and XY, there can be XXX, XXY, and X and many others besides.
Does this have to do with being transgender? From a genetic perspective, are there more sexes than male and female, or is everything else just classified as a disorder?

Women with Turner syndrome have just one X chromosome but women usually only have one working X because of X-inactivation. Why do women with one X chromosome have any symptoms?
