Octuplets! Second Succesful birth of 8 babies in US history

In the US, the second successful birth of Octuplets was recorded this week! This is only the second successful birth of 8 babies in the history of the US!

Thanks to fertility drugs and techniques, high order of multiple births have become a lot more common. A multiple birth is one where more than one baby come out. Higher orders of multiples are what we call any birth with more than 2 babies.

These babies can either be identical or fraternal, which means that they either share the exact same DNA, or share DNA on the level that regular siblings do. Unless they have different genders, multiples usually never get to figure out for certain if they are truly identical or fraternal.

The only foolproof way to know for certain that you are identical or fraternal twins is by taking a twin zygosity test. With this test, the results are irrefutable.

Twins, triplets, quadruplets, quintuplets, sextuplets, septuplets, Octuplets!
