30 Amazing and Interesting Facts about Twins | Amazing Facts 4U

- Fraternal twinning is genetically predisposed while Identical twinning is random. Fraternal twinning is the result of a woman releasing multiple eggs at the same time and is largely the result of a genetic predisposition. Identical twins, however, are the result of a random split of a single egg. In recent years, the number of fraternal twins has risen in response to fertility treatments, while the number of identical twin births has stayed the same. Fraternal twins don’t share identical genetic material.
- Twins can have different gestational ages when it comes to fraternal twins. One egg may be fertilized days before the other, leading to a difference in the age and development of the twins.
- Massachusetts has the most twin births of any state in America.
- China has the lowest rate for multiple births averaging 1 in 300.
- Identical twins are the result of a random split of a single egg and cannot be genetically predisposed.

- Fingerprints are not solely generated based on DNA. When identical twins are conceived, they start out with the same fingerprints due to same DNA , but during weeks six through 13 of pregnancy, as the babies start to move, they each touch the amniotic sac, and unique ridges and lines are formed on each twin’s hand that result in different fingerprints.
- For polar bears, twins aren’t unusual at all. In fact, they most commonly give birth to twins, and rarely deliver single cubs or triplets.
- It’s possible that twins can have different dads. In 2009, Mia Washington gave birth to twins who have different fathers which is said to be a one-in-a-million occurrence.
- 40% of twins invent their own special language. These languages are called autonomous languages. These autonomous languages are formed when two very close babies are learning how to speak a real language alongside one another and naturally often play and communicate with each other. The made up “languages” often disappear soon after childhood, once the children have learned a real language.
- About 25% of identical twins are called mirror image twins. This means that they are, in fact, identical, but only in the way that your reflection in a mirror is an identical image of you. For example, if one twin has a mole under her right eye, the other will have it under her left eye. Scientists think this is due to the fertilized egg splitting later than the norm for identical twins, around nine to twelve days after fertilization.
- Although it’s difficult for humans to differentiate between identical twins, this isn’t the case for specially trained German Shepherds, who can pick up on scent variations between both identical and non-identical twins.
- Twins do not have to be born on the same date. In fact, they can be born surprisingly far apart.
- Amy and Katie are twins that were born 87 days apart. Their mother’s water broke a mere 23 weeks into pregnancy. Amy was born four months premature, weighing little more than one pound and fighting for her life in an incubator while Katie was struggling to survive in the womb.

- One of the easiest ways to tell identical twins apart is their belly buttons. Belly buttons are scars from the detachment of the umbilical cord, so they aren’t caused by genetics and each one is slightly unique.
- Identical twins can make master criminals. Apart from their fingerprints, identical twins are 99.99% identical on a DNA level. In January, 2009, $6.8 million worth of jewelry was stolen in Berlin. The single suspect left behind sweat beads, which police extracted DNA from and tracked down to two people – Hassan and Abbas both identical twins. Both denied responsibility, accused the other, and because police couldn’t identify which of the twins the DNA belonged to, both ended up walking free.
