Seeing Double?
It’s been a while since we’ve seen one of these guys, so we’re doubling up on our panda intake today. Have you gotten your double dose?
When it comes to human twins…
- A whopping 22% of twins are left handed. Compared to 10% among the general population. Rates of twin births vary by location.
- Certain areas of the world and our own nation have much higher rates of twin births than other places. For instance, if you live in Massachusetts, New Jersey or Connecticut, the twinning rate is 25% higher than the general populace. On the flip side, Hawaii and New Mexico have a twin birth rate 30% lower than that of the national average.
- About 25% of identical twins are called mirror image twins.
- There are actually 7 different types of twins. They are: identical, fraternal, half-identical, mirror image twins, mixed chromosome twins, superfecundation, and superfetation.
- The longest recorded gap between twin births is 85 days.
- Identical twins have almost identical brainwave patterns.
- Fraternal twinning is genetically predisposed. Identical twinning is random.
- 27 lbs and 12oz is the heaviest combined birth weight of any set of twins. (Nursing School Blog)
