(illustrated with a picture of a flecky-eyed baby)



If that link doesn't work, the article can be found via the strangely named :


On the subject of buying people in the EU, I wonder where Chemello and Vaz are these days...?

This is the correct first link.

I have heard of the other case mentioned in the link of the American woman Lydia Fairchild; there was a TV programme about her.

Please excuse me if I'm having a senior moment (I probably am) but, if the "real" parent is an identical twin who was never born, wouldn't the DNA be the same anyway?

I've tried to understand chimaerism before in relation to this case but could never quite grasp it. That article makes it very simple - thanks for posting.

Freedom, identical twins are formed when one fertilised egg splits into two embryos and yes, the DNA is the same for each twin.

Non-identical twins share the same womb when two separate ferilised eggs happen to implant in the uterus at the same time. These do not share the same DNA. Chimaerism can happen in this case if the two eggs do not implant separately but instead fuse together. The resulting embryo will therefore have 2 sets of DNA.

I think Smile .

I very recently read an article about IVF and it said ,that the chil dborn can have more than one set of dna,the mother womb can leach out from womb ,therefor is another dna as well as father and mother of egg fertilized before using it to another couple. Amazing to hear eh ? joyce1938

Chicken chimaera...

I hope this link works - this article's about gynandromorph forms of birds and insects.


I used to have a chicken that was a hen on the left side, and a rooster on the right -

(the closest description I could come up with for its nature was 'ladyboy')

- two creatures in one, split down the middle... Strange, and almost magical.


Yes, Joyce1938 - interesting concept!


This is the correct link.

Even weirder genetic oddities...

Post  Rosa canina on Tue 24 Nov 2015, 9:05 pm

I was looking up gamefowl crosses last night when I came across this site :

www.macroevolution.net/chicken-duck-hybrids.html

'Chuck, the chicken-duck' looks quite convincing to me -

- no idea about the cabbits, though - and some of the possible hybrids

are really rather mindblowing...! Interesting stuff.
