What about somebody who has a 46,XX/46,XY "true hermaphroditism" genetic condition caused by chimerism, what gender would somebody like this be considered?
"46,XX/46,XY is a
chimeric genetic condition caused by having two distinct cell populations within the body. The chimerism arises
in utero from the combination of an XX
zygote and an XY zygote (which otherwise would have developed into twins) into a single
embryo.
[1] It is not to be confused with
mosaicism and
hybridism. 46,XX/46,XY is sometimes associated with
Intersex conditions such as ambiguous genitalia and
hermaphroditism."
