I read an article about this in Twins Magazine. It was in the section "Zygosity Puzzle". I searched the magazines website and found the issue. You can order it for $3.00. Here's the link:

http://www.newslettersonline.com/use...412/fp=3/tp=33

It's the March 1, 2003 issue. I'm also going to check to see if I still have that issue. I gave some of them away to a friend who was pg with twins but I did keep some and she gave some back. I'll check for you and let you know.

From what I remember from the article, the way it happens is one egg is fertilized and it is a boy baby. The egg splits into monozygotic boys. Then one of the babies develops into a normal boy while the other one loses it's boy chromosome and develops into a girl baby that has Turner Syndrome. Turner Syndrome causes girls to never hit puberty or be able to have children. I don't remember the actual stats of it either but it was extremely rare.

Hope this helps you!!

My link didn't work for you. This is exactly what I did. I went to www.twinsmagazine.com. Clicked on "Search Magazine" then typed in "zygosity boy girl" in their search engine and the dates between April 1, 2002 and January 1, 2004. The first page had the magazine you're looking for which is the March 1, 2003 issue. The article was "Zygosity Puzzle".

I also read a study of twins being "half identical" (I'm sure there was a technical term LOL) I believe it was also in twins magazine.... basically (IIRC) that the egg split BEFORE being fertilized - so the mitochondrial DNA would be id but two different sperm fertilized the ID eggs. so the twins would only share half the id dna. pretty sure that's it.

I'm Andrea - I have three boys - 12 year old twins & an 11 year old

Those are called polar body twins (I think).
