Twins? =)
Hello, hello!!!
Today I want to share some facts about twins, triplets or quadruplets...huhu
Do you know that...
• Identical twins share the same DNA, but will have their own fingerprints!
• About 25% of identical twins are called mirror image twins. For example if one has a mole under her right eye, the other will have it under her left eye.
• Chances of having a twin pregnancy naturally is increased by maternal age ( 30+), genetics and number of previous pregnancies.
• According to the National Center for Health Statistics the number of multiple births has increased about 74% since 1980.
• The average length of a twin pregnancy is 36 weeks and 3 days.
• The average weight of twins at term is about 2.5 kg
• The average or recommended weight gain for average sized mothers of twins is between 15.91-20.45 kg
• Studies have shown that mothers who gain about 10.91 kg by week 24 have reduced their chances of giving birth either prematurely or to low birth-weight babies.
• Women pregnant with twins will have more ultrasounds, tests and prenatal appointments than women pregnant with singletons.
What are the differences between identical and fraternal twinning?
Identical twins develop when a fertilized egg splits. Depending on when the split occurs will determine if the twins share a placenta, with either one or two chorions and amnions, or if they each develop their own placentas. In general, the later the spit occurs, the more likely that the twins will share one placenta.
While fraternal twins are the result when two different eggs (ova) are fertilized by two different sperm. This leads to the development of two separate placentas, each with its own chorion and amnion. Fraternal twins are more common than identical twins and account for about 2/3 of twin pregnancies.
What about higher order mutiples?
The same factors occur with higher order multiples, with either multiple eggs being fertilized or one or more fertilized eggs splitting.

What about higher order mutiples?
The same factors occur with higher order multiples, with either multiple eggs being fertilized or one or more fertilized eggs splitting.
For example, in the case of triplets, you could have:
- three separate eggs being released and fertilized by three different sperms (fraternal triplets)
- two separate eggs being released, with one splitting after it is fertilized (2 of the triplets will be identical and the other fraternal)
- the last type is the most rare, with one egg being released and splitting three times after it is fertilized (identical triplets)
Subhanallah...Just knowledge...=)
