...R and G are identical. Absolutely, completely and utterly.
The test is 99.99996368% accurate, which is pretty irrefutable in my book. The zygosity test measures 16 DNA markers, each of which has a number assigned to it. Every single marker for each child is the same. They are monozygotic.
So, they aren't the result of a piece of hereditary wizardry (I'm now hoping my sister gets the non-ID twins!). They are a rather marvellous freak of nature and I mean that in the best sense.
I'm finding it all a bit mind-blowing to be perfectly honest. Within two days of 'the deed', one egg split and became two. They had a falling-out (that's siblings for you) and took refuge in separate sacs, where they stayed for the next nine months, growing entirely independent of each other. That's pretty amazing.
I'm sitting here realising how unbelievably lucky I am. There are so many variables to consider when carrying identical twins. All of the following are possible: same sac, tangled umbilical cords, increased chance of early labour, assorted heath difficulties, twin-to-twin transfusion syndrome and many others that I haven't thought of - and I dodged every single one.
It looks like dh and I have got an awful lot of explaining to do. We've spent nearly two years telling everyone that the girls are non-identical, even in the face of some pretty strong opposition and now we have to backtrack and say 'Guess what? You were right and we were wrong. They ARE identical! Ha ha ha!'*
*I'll insert my Mummy disclaimer here though. Genetically they may be absolutely the same (and rather frighteningly like their father) but to me they will always be different. They remain, as they always have been, just R and G.
