There is an increased rate in the number of twins born every year. This year American Women have given birth to more than 140,000 sets of twins which is much higher than the previous years. Here are few facts about twins which everyone must know:
To Identify the twins apart:
To determine each person of a twin, just look at their belly buttons. Navels are the scars which are detached from the umbilical cord after birth. Hence they are not genetic. Also, you can determine them by their fingerprint as both will have unique fingerprints.
Twins can have different dads:
Heteropaternal superfecundation occurs when a woman has sex with more than one man during ovulation. Sperm from each man fertilizes an egg, resulting in twins. Though this phenomenon is common in dogs and cats, it’s extremely rare in humans.
The chance of having twins is much higher:
The birthrate for twins has increased 76% since 1980, an uptick that some experts attribute to older women having children (women in their thirties are more likely than women in their twenties to have twins). Or maybe women are getting taller: A Long Island, Jewish Medical Center study, found that women who birth twins or other multiples were, on average, more than an inch taller than women who only birthed one child at a time.
Fetuses that share a womb and a birthday aren’t necessarily twins:
An extremely rare condition called superfetation occurs when a pregnant woman continues to menstruate and a second embryo forms. Often, the fetus conceived last is born prematurely, while the fetus conceived first is carried to term, but in some cases, the babies are born on the same day.
Twins speak their language:
What sounds like kids’ babbling could be cryptophasia, a language developed between twins that only they can understand. Research published that in the journal Institute of General Linguistics found that twin babies often use each other to learn vocabulary. The study estimates that up to 40 percent of twins create a private language.
Some twins are mirror images of each other:
When a fertilized egg splits later than usual, identical twins’ appearance and other traits can reflect each other. For example, one twin may have a birthmark on her left arm, while the other twin has a birthmark on her right or one twin may be right-handed and the other left-handed. In extreme cases, one mirror-image twin’s organs may be reversed, with the heart on the right and liver on the left.
Twins may help mom live longer:
University of Utah researchers who studied birth and death records between 1800 and 1970 found that the mothers of twins tend to live longer than moms without twins.
Twins bond in the womb:
If you’ve ever seen this video of newborn twins being bathed for the first time, it won’t come as a surprise that Twins may begin interacting the in the womb as early as 14 weeks into a pregnancy.
