Oh my! You look like me! |
However, today on a twins online board, I read in someone's post that 20 to 30 percent of di-di twins are identical. That range seemed a bit high, so I did a little research (slow day at work). The actual fact is that 20 to 30 percent of identical twins are di-di. And about 33 percent of all twins are identical, which gives us an actual rate of about 10 identical sets for every 100 di-di twin sets. Roughly.
So it turns out we have a 10 percent chance of having identicals. Crazy!! This only happens when the egg splits within three days of fertilization. But it does happen! I find this both cool and terrifying. Those girls switched on their parents so easily in the movie! I know they say parents always know, but the twin board has led me to believe it's quite otherwise. One woman even had to bring her identical boys to the doctor to have him figure out which was which (they were very young at the time so the boys couldn't tell her).
And the only way we'll know--if they are the same gender--is by a DNA test. Crazy! Of course, if they are boy-girl, we'll know immediately that they are fraternal.
But this could be our future:
Imagine waking up to that in the middle of the night!
