Our C word for today is chimera, a rare and interesting intersex
condition. Chimeras occur when fraternal
twins fuse together in utero at an early stage of development. The result is one individual with two
different sets of DNA. Some groups of cells
in their body have one set of DNA, and other groups will have another set.
It is important to realize most chimeras are not
intersex. If both twins are the same
sex, obviously they will not be. Even if
the twins where different sexes, chimeras DNA tends to stay within different
organs and systems, having a male liver and female kidneys for example. Thus even if they genetically have male and
female cells, they usually develop along the lines of whichever genetics their
reproductive system is. That being said,
there are rare cases where a chimera will have ambiguous genitalia and a mixed
genetic reproductive system.
It is interesting.
Many people assume this is how all intersex people came to be. My mom even said when I was a baby, people hypothesized
that I was twins (I’m not). Chimeras
seem to play into an old cultural myth that a “hermaphrodite” must essentially
be two people, or have some sort of soul or essence of two people (look up two
spirit). Obviously this doesn’t reflect
reality at as most intersex persons are not chimeras and most chimeras are not
intersex (in fact most chimeras don’t know they are chimeras).
