Are they, or aren't they?
I have always been doubtful that my twins are identical because there are so many physical differences. I am watching a VERY interesting show on National Geographic channel about multiples right now, and I heard that many "identical" twins have slight physical differences.
When a mother's egg splits, the outer cells -- mitochondrial cells -- can sometimes mutate as the embryo/fetus matures. This can cause physical differences such as: build, height, weight, etc. Apparently, scientists are reluctant to use the term "identical" these days. They prefer to use the term "mono-zygotic"... meaning of one egg and one sperm.
AT LAST! An answer to my questions!
My girls were mono-chorionic and di-amniotic with one placenta (one outer chorion membrane sac that the placenta fuses to, and each had her own amniotic sac). Apparently, one amniotic sac is rare even in identical twins. Also, because they are the same gender, all arrows seem to point to identical.
What do you think?
Coincidentally, in all three pictures, Kaitlyn is on the left and Ainsley is on the right... Couldn't you tell?

Hopfully she'll keep that for the rest of her life or I'll never get it straight
And this is also how I know we are related.
