“this baby came out of you but im not 100% sure its yours”

Funny thing - a woman who applied for welfare after her husband left her hadto supply DNA evidence he was actually the father. The results: he was definitely the father, but she wasn’t the mother. Her children were removed from her custody and she was sued for fraud, even though she insisted they were her children.

Turns out, she wasn’t a surrogate or a kidnapper (the two most obvious explanations) - she was a chimera. As an embryo, she fused at a very early stage with her twin, forming one individual. Her ovaries apparently developed from cells that had originally belonged to her vanished twin. Later on more tests showed that while the woman’s skin and hair DNA did not match her childrens, DNA taken from her cervix did.

This went from stupid to really interesting in point 5 seconds.

We don’t actually know how many human chimeras there are because most of the time you can’t tell.

However, some cases of intersex and even some trans individuals may be chimeras that result from the fusion of two embryos that have different genetic sex. This may also explain why some female athletes fail a sex test. (Other possibilities include genetic transcription that resulted in the loss of the SRY gene from the Y chromosome. The SRY gene is the actual switch that results in the development of a male phenotype).

Chimerism is also seen in animals.

This is Dunbar’s Gold. As you can see he looks like a brindle dog.

At one point he was bred to a mare called Sharp One, who also had the same brindle pattern, in the hope that they could breed more brindle horses - which are vanishingly rare.

Both horses are Quarter Horses, and the breeder sent in a gene sample from the foal for typing to allow him to be registered.

The test showed that the foal was related to neither his sire nor his dam.

They even did the test twice. Most cases of failed genetic testing are a sample mixup (either the hair or the semen used to produce the foal).

It turned out Dunbar’s Gold had had to be tested three times to get a good sample - and the third time was a blood test not the hair follicle test normally done. On top of that, when they looked at his gene type again they realized something rather important to a stallion was missing - he had no Y chromosome.

It was eventually established that both horses were chimeras and that in Dunbars Gold two different gene types existed in his skin and coat (one male, one female, just to prove that happens). Each gene line had a different set of color genes, but both matched properly to his parents. His foals, of course, all matched to the male gene line.

When they tested Sharp One’s other foal they discovered she was producing eggs from both of her gene lines. (Something which could also happen with a human chimera).

Science. Is. Fun.

If you’re trying to catch a housecat that’s gotten outside, don’t forget: they’re an ambush predator and you’re a persistence predator. You have several times more endurance than they do - use that to your advantage! Don’t run after them; that’s playing to the cat’s strengths, and vigorous pursuit may cause them to hide. Instead, follow them at a brisk walking pace until they get tired and need to have a lie-down, at which point you can simply pick them up and take them home.

When Harry becomes the DADA professor, kids constantly ask him for an autograph, but he refuses, saying the only thing he’ll autograph is a detention slip. Eventually, though, he starts carrying around a stack of autographed pictures of Ginny, which he gives out when people ask for an autograph. It gets really popular, so he starts mixing it up with autographs from other people, mostly Ron and Hermione. But the students love it, so he adds more. Soon he’s giving out autographs from like fifty different people, including all the teachers at Hogwarts, and a bunch of other random people like Luna, Lee Jordan, Oliver Wood, etc. He even has some fairly rare ones from Krum and Fleur. It becomes a game in Hogwarts to collect all the autographs, like chocolate frog cards. Some of them are more limited edition than others, like signatures from all the ghosts (though Harry won’t reveal how he managed to get those). George starts to offer a discount at Weasleys’ Wizard Wheezes (and a prize autograph from Peeves, who will only sign Bertie Bott’s scratch-and-sniff cards) to anyone who can prove they’ve collected the whole set. Harry provides him with up-to-date lists of autographs to check against. Every Hogsmeade weekend there’s a line of Hogwarts students in WWW’s Hogsmeade branch trying to get the discount.

At some point a seventh year comes up to Harry and asks for his autograph, but not as the Savior of the Wizarding World, but because they now have the autograph of every other Hogwarts teacher and want Professor Potter’s to go with them. Harry–trying not to tear up–agrees, but only in exchange for the student’s signature. He begins offering this deal to all departing seventh years, his autograph in exchange for theirs. He tells them it’s in case they ever get famous, so he can add it as a limited edition autograph, but really he keeps them all in a big binder just for himself, to remember all his students. (A couple times, though, when a students does become famous, he will contact them and ask if they’d like to be added to the game. So far no one has said no.)

When Teddy starts at Hogwarts he begins a black market autograph trade because he has access to a lot of the people Harry gets autographs from. Harry’s other three children proudly continue the trade when they get to Hogwarts. They’re all secretly aided by Ginny.

Anyone else thinking that pre-autograph collecting, people were getting A LOT of detentions from professor potter because they all acted out to get his autograph?😂
