Are identical twins actually exact replicas, facial feature wise, of each other? Well, this photographer set out to find the answer, and the results aren’t too surprising. For those who don’t already know, “twins can either be monozygotic (“identical”), meaning that they develop from one zygote that splits and forms two embryos, or dizygotic (“fraternal”) because they develop from two separate eggs that are fertilized by two separate sperm.” Continue reading to see more incredible side-by-side comparisons.
7 Interesting facts:
- In 1980, one in every 53 babies born in the United States was a twin. By 2009, that number had risen to one in 30, according to new research released by the National Center for Health Statistics. Over those three decades, the twin birth rate (number of twins per 1,000 births) rose 76%.
- Chances of having a twin pregnancy is increased by maternal age (30+).
- Fraternal twining is genetically predisposed and the result of a woman releasing more than one egg at the same time.
- Identical twins are the result of a random split of a single egg and cannot be genetically predisposed.
- Male twins will not have twins unless their wives have the ability to produce two eggs.
- Identical twins share the same DNA but do not have the same fingerprints.
- 1 in 250 pregnancies can result in identical twins.
