The more confused we get.

And that's a big part of why Republicans favor education - and a voting public - that is rooted in 1950's high school biology assumptions.

A rapist whose DNA from a saliva swab excluded him. Everything else pointed to this suspect so Gil Grissom (played by William Petersen) was confused until he saw some striated marks on the man's back. That led him to take DNA from another source, proving the man was the rapist.

I think that's my favorite episode.

Compare like to like. (I'm assuming they had a forensic sperm sample.)

I believe wasn’t a chimera so much as he had De La Chapelle syndrome.

I checked and I think it was the episode was called 'Bloodlines'. I can remember Gil bringing up, MAYBE, the possibility of a Chimera. It absolutely fascinated me because I'd never heard that term applied to a human.

Thank you for posting this, my dear multigraincracker!

of DNA and depending where that DNA was it could make a baby come out with a set of genitals that did not match the DNA of the baby's brain. That would happen when a fraternal twins absorbs another twin of the opposite sex.

i lost a twin that way, and always assumed it was a boy.

one and if one dies the other will naturally absorb it.

dumb. but assumed it required a single placenta. i guess that makes it easier, but i'm sure there's overlap. now i'm curious about how it works, exactly.

I have read this before somewhere. I wish I knew where, but it’s been quite a while ago.

could a really confuse some (not pointing to any specific group) not so open minded among us. My brother was a research scientist specializing in diabetes and his wife still works in stem cell research last family get together we discussed this very subject briefly.
Bro mentioned that if only more people could understand even a little…but his IQ blinds him to others comprehension.

g’d morn MGC.

There are natural variations in human sexuality that prove there are more than 2 sexes. It isn't "evil" or "unnatural" to be different, but they take a line from the bible and interpret it the way want it to be as proof.

bigoted fools are not bigoted because of their reliance on facts, they are bigoted because of their reliance on beliefs. They may use particular facts to reinforce their beliefs but they may also ignore facts which contradict their beliefs. Because their bias comes from beliefs and not from facts, exposing them to more facts rarely changes their bias.

and just think 'live and let live' and not be judgemental about it.

That explains so much.

Biology just won't follow our foolish notions of what's normal and what's not. It refuses to be put into nice, neat, little boxes.

A similar case....

Answer me this, Christian forced birthers, where is her sib's "soul?" Since "life" begins at conception, does she get to vote twice? After all, by their own definition, she is two people in one. This is what happens when religion intrudes on reality and doesn't stick to it's lane in fantasy world.

Bone marrow transplant may change dna?

A cheek swab would show your own DNA. However, a blood draw would show the DNA from whoever donated the marrow, assuming that the donation is allogenic - IOW, not a self (or autologous) donation.

It's been pretty well documented that women* who have carried a male* fetus have a good chance of his cells passing through the placenta and "colonizing" (the researchers' word) locations in her body.

* for the sake of a simple example I'm assuming they're all cisgender, with typical XX or XY karyotypes.

and his blood type is in the process of changing.
When he needs blood transfusion he gets
O negative now, so there won't be issues.

Rhetorical question, of course.

I was actually (slightly) familiar with the concept of chimera. (I think maybe in relation to 'extreme' tortie patterning in domestic cats?) And, while still comparatively rare (among humans, probably less so in other life forms) - it does tend to puncture some of the smug certainty of the mechanical 'A+B' thinking.

Cardinals with male and female genetics...

There have been several published papers on women who successfully carry a pregnancy to term and turn out to have XY chromosomes.

One was assigned female at birth, went through a typical girl -> woman childhood and puberty, got married, had a child and then was found to have XY chromosomes. But the really interesting part is that her daughter also has XY chromosomes.

Before maybe 8-10 years ago, chromosome testing was expensive. So if someone gave birth, it was simply assumed a karyotype test would come back XX.
But since then, it's become much, much cheaper so more testing is done. And it turns out that it's unusual, but now well documented that a woman can have XY chromosomes.

Naturally, these last ten years or so is also the time period in which Republicans and other conservatives have tried to appropriate concepts such as "follow the science" without actually doing so. Because the science is so very inconvenient for many of their now-bedrock assummptions.

In 2002, after applying for government assistance in the state of Washington, Lydia Fairchild was told that her two children were not a genetic match with her and that therefore, biologically, she could not be their mother. Researchers later determined that the genetic mismatch was due to chimerism, a condition in which two genetically distinct cell lines are present in one body. The state accused Fairchild of fraud and filed a lawsuit against her.

Following evidence from another case of chimerism documented in The New England Journal of Medicine...Fairchild was able to secure legal counsel and establish evidence of her biological maternity. A cervical swab eventually revealed Fairchild’s second distinct cell line, showing that she had not genetically matched her children because she was a chimera.

Fairchild’s case was one of the first public accounts of chimerism and has been used as an example in subsequent discussions about the validity and reliability of DNA evidence in legal proceedings within the United States.

The Lord works in mysterious ways.

...that scribes' hands were guided by God & therefore the text is pretty close to infallible.

Over and over it could've been changed to the binary, "He made them man OR woman" (emphasis mine). But instead it's "He made them man AND woman" overtly recognizing that human sex dimorphic traits over populations chart out as two highly overlapping bell curves.

For the Bible folks:::

Eve was the first transgender. Originally 100% male.

God was OK with it.

For Mary to conceive & bear a child without sperm, it had to be parthenogenesis, ie an egg that is genetically identical to the mother that starts dividing and develops into a fetus. Therefore Jesus had to be a trans man.

including and especially BIOLOGY

We group things into this bucket or that one for our convenience in thinking and communicating, and over time we forget that Nature is much more creative and messy. We see what we conceptualize and ignore that not everything fits in the bucket.

Even with computers, whose 1s and 0's are held up as the ultimate example of binary...it's still just an abstract concept, not a reality.
In the most basic example, a zero is anything below say, 0.3 volts. And a one is anything above 0.7 volts. Note the gap; the voltages are thresholds, where anything above or below can safely be assumed to be the intended logic value.

I am one of those women who was a fraternal twin. I was in my Mom's uterus first! My fraternal twin was a male, he didn't make it for very long. This much I've known from Mom since I was a teenager. But now you've got me wondering if I'm carrying some of his genetic markers (as well as some of his traits). I always laughingly remarked my personality, even in the womb, was so strong, I overpowered him. But now, I wonder... if most of my assertive traits (re: male-like traits) came from his genetic nature?

I'm 66 years old, have always presented as female, use female pronouns, am a mother and grandmother, and am happy as such. But I will admit, the bi lifestyle has never been a turnoff for me, and have often said should anything happen to my husband, I'd never marry again, but would probably seek a strong female relationship, instead.

Would any of these ancestry type tests they advertise pick any of this stuff up? I've always ignored these things because I don't trust them. First, I don't trust that routines would be hardened enough to get to -me- what is intrinsically -mine- rather than someone else's. Also, I don't trust they don't turn results over to some database someplace. Since I already have a chronic autoimmune disease that has me on meds, including pain meds, I'm on databases both state and federal, no doubt. It scares the bejesus that someone, someplace, could strip me of meds I need to live.

The geek in me wonders if this type of situation has anything to do with the activation of the autoimmune gene in me, tho. I wonder if any study has been done researching this aspect. So little is known while so many of us suffer autoimmune diseases. And those of us who suffer autoimmune diseases that don't kill us (like me) are at the butt end of the science... and the compassionate nature of me understands... the painful days I have scream out in frustration, tho... I often wish this had hit me earlier. I might have made the science of biology and medicine my majors, rather than psychology, and then made a different career than the one I chose in computers and public service. So many things I'd do different if I were younger, knowing some of the things I know now! (LOL)
