Fraternal twins
There is one particular power though which twins possess, longevity. Fraternal twins live longer than singletons and identical twins longer still. Male identical twins on average, saw the most benefit. The rarity of twins has inspired many myths about them.

Can twins be born 7 years apart
Medically, this 7-year defect is very rare. Twins are typically born with a bit of a delay — a few minutes to a few hours.
Do twins live as long

What is the rarest twin
Such twins, known scientifically as 'MoMo', an abbreviation for monoamniotic-monochorionic, are some of the rarest types of twins, making up less than one percent of all births in the United States, noted the statement. It also stressed that such MoMo twin pregnancies have a high risk of fetal complications.

How rare are twins
What are the chances of having twins Just over 3 percent of babies in the United States are now born in sets of two, three or more, with the majority — about 97 percent — of these multiple births being twins. So your chance of having twins is about 3 in 100.
How were twins born 87 days apart
Maria Jones-Elliot went into labour three months early with Amy, who weighed just 1lb 3oz; her sister Katie did not arrive for another 87 days. Once she had given birth to Amy, Maria's contractions stopped and despite efforts to induce her the following day, Katie remained in the womb.

Are boy girl twins rare
Mixed-gender twins are the most common type of fraternals, some 50 percent are boy-girl. To understand this combination: Males have XY chromosomes, females have XX chromosomes. You have a girl twin when the father's X chromosome combines with the mother's X chromosome.
Which twin is older
As a parent of twins, I'm pretty sure that you know the answer to the question “which twin is older” It is, of course, the child that was born first.

| 6 | Sextuplets |
| 7 | Septuplets |
| 8 | Octuplets |
| 9 | Nonuplets |
Are twins 100% the same
The DNA of monozygotic twins tends not to be 100% identical, and epigenetic and environmental differences further widen the gap between twin pairs. It's not nature or nurture; it's a complex interaction between our genes, our environment, and our epigenetic markers that shape who we are and what illnesses befall us.
Are twins 100% related
Identical, or monozygotic (MZ), twins have 100 percent of their genes—including those that influence risk for alcoholism—in common, whereas fraternal, or dizygotic (DZ), twins share (on average) only 50 percent of the genes that vary in the population (see figure). Common Environmental Sources.
Can twins be born 2 years apart
Twins with different birthdays are rare, and the chance of twins being born in different years is 1 in 2 million, according to the news release by Natividad. Though the incident is rare, it's not the first time twins have been born in separate years.
Can siblings be born 11 months apart
The term “Irish twins” refers to siblings who are born within 12 months of one another. This is especially true for children born in the same calendar year, or children who would be in the same grade of school. However, children born within 18 months of one another are still often referred to as Irish Twins.

It also stressed that such MoMo twin pregnancies have a high risk of fetal complications.
What is 12 twins called
If the 12 – called duodecaplets – are all born alive they would represent a medical miracle and break the record of American mother Nadya Suleman, who recently gave birth to the world's longest-surviving octuplets.
Do all twins have same IQ
The mean absolute difference between twins is 6.60 (SD = 5.20), the largest difference being 24 IQ points. The frequency of large twin differences is no more than would be expected from the normal probability curve.
Do twins have same IQ
Because identical twins share all of their genes, their measurements of IQ and sleep time will be more similar the bigger role genes play in it (i.e., differences between two identical twins must be caused by the environment because their genes are the same).
Were there twins born in 1999 and 2000
It happens every year. And while remarkable and special, some other twins can make an even greater claim to fame—being born in different millennia. The Wallman twins from Indianapolis, Indiana were born at 11:59 p.m. Friday, December 31, 1999, and 12:01 a.m. on Saturday, January 1, 2000.
