Sorry, Science says Sex chromosomes do not change over the course of medical transition for a transgender person. Male and Female chromosomes do not change, they will always remain the same in a human's body. If a person is born with both, you will still have a prominent chromosomes that identifies the actual sex. Changing how one identities sexually doesn't change science. So no, Science doesn't say it is technically correct to say there are more than two genders period.
Just to be clear, Science supports man caused climate change period. No debate needed. Science supports only two sexes exist in Humans, that has never changed. I'm not sure because a person can have both.
Okay, I got it!
