On Facebook I am in loads of twin Facebook groups. We support each other and there is always another twin mum around for help and advice or a shoulder to cry on. I was reading a post yesterday with a random identical twin fact in that made me think and it made sense once I actually read and thought about it.
I have identical twins which come from one fertilised egg split very early on in the pregnancy (usually in the first 14 days after conception). My twins were MCDA (modi – Monochorionic Diamniotic Pregnancy). They shared a placenta but had a very thin membrane separating them, several times they thought they were in one sac not two as it was that thin. The monitoring for an identical twin pregnancy is far more intense and you must have lots more scans and checks.
There is loads of research and information on the internet about the different types of twin pregnancies. I would highly recommend you do some research if you find you are having twins. You need to know what you are dealing with so you can advocate for those little bundles of joy and get the best care possible.
But all the above said and now we have established my bundles of joy are identical I read a post yesterday about if Edward and Euan have children they will be genetically siblings rather than cousins. How bizarre I thought, but when you actually think about it they have the same (well almost the same) DNA.
Off in search of some answers I came across a great article on a website called Genteics.thetech.org
They had this to say, but you need to read the full article which shows you the DNA make up it’s super interesting.
Since you both have the same DNA, this is almost like the two sets of children have the same moms but different dads. In fact, this is why at the DNA level they are really more like half siblings instead of first cousins. They share 25% of their DNA (and genes) instead of the usual 12.5%.
Legally your kids and your sister’s kids are first cousins but at the DNA level they are half siblings. They share twice as much DNA as run of the mill first cousins!
How cool is that – you can read the full article about DNA in twins here. I found it super fascinating.
So there you have it my random identical twin fact for a Thursday afternoon. It has inspired me to go and check out some more interesting twin facts. Watch this space as I find more.
Do you have or are expecting twins?
You must check out these hilarious questions people have been asked when out and about and please do add any in comments that we have not heard of.
