What do you say to the tetragametic chimeras who have both fully XX and fully XY cells in their bodies? The embryos of two fraternal twins, a brother and a sister, merge early during gestation into one being, which then becomes our subject in question. Speaking of science.

The pictures are of different skin tones seen in black/white chimeras, but there also exist boy/girl chimeras.

The percentage of these is so low as to be insignificant. The occasional anomaly does not warrant the number of those who believe they were ‘born with the wrong body’. Chimeras exist but are astronomically rare. And, as you point out, they were two people who ‘accidentally’ merged. Not one person (originally).
