Types Of Identical Twins Pregnancy
If you have identical twins, will they both develop the same genetic/inherited disease at the same point?
Depends: If it's something that fully expresses itself with no modification (such as huntington's), yes. If it's going to express itself but is lifestyle-modifiable (type ii diabetes), timing will differ. The diseases for which there's a genetic component (diabetes, lupus, multiple sclerosis, many others) have only one twin affected more often than not -- you can find details. ...Read more
When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more
Yes: Fraternal twins are 3 times as frequent as identical. Fraternal twins happen when there is double ovulation and 2 eggs get fertilized. They are the type of twins that run in families. Identical twins come from 1 fertilized egg which separate in early gestation. Depending on when they separate, the babies can be in 2 distinct sac (di/di), 2 sacs within a shared sac (mono/di) or 1 sac (mono/mono). ...Read moreSee 1 more doctor answer
Some do some don't: If two twins share the same sac, they're identical. (almost always works.) the pathologist who examines the placenta can tell. Identical twins can have two sacs, or one sac; if there are two sacs, there can be one or two chorions. Fraternal twins won't share chorions or sacs. ...Read more
Can an orgasm kill an unborn identical twin? Should orgasming be stopped due to identical twins or MoMo twins?
No, if all is normal: A fetus can die after the pregnant woman has an orgasm, but can also die before she has an orgasm. A fetus can die after the woman eats a peanut butter and jelly sandwich. All these things do happen, BUT are they related? The answer is NO, unless the woman has a problem that causes two things to be related (such as having a peanut allergy, and a life-threatening reaction after a PB&J sandwich). ...Read more
After healthy heart rates are identified in identical twins, what is the probability of a vanishing twin?
Fairly common: A conservative estimate of frequency is that vanishing twin syndrome occurs in 21-30% of multifetal pregnancies. More commonly identified now that first trimester ultrasound is widely used. There are no known preventive measures since the loss usually occurs because of cord implantation abnormalities.

My Husband has multiple sets of fraternal twins on his side and I have identical twins on my side, is the twin gene carried on the male side or woman?
Female Side: Genetic increase for twins is due to female tending to ovulate more than one egg at a time, so trait is for fraternal twins (not identical) and carried by mother. ...Read more
Yes: Actually this is slightly more common after day five transfer ~1%. Since the embryo is in nearly hatching or hatching, the transfer "pressure" can cause the embryo to split into identical twins. This is one of the disadvantages of day 5 transfer. Good luck. ...Read more
Both: A fertilized egg cell will split into two separate embryos, and grow into identical twins. A common misconception about identical twins is that the trait for having them is passed on to future generations through the mother's genes. But the truth is science doesn't know the reason why identical twins occur. At this time, we can just say that they're examples of a nine-month double miracle. ...Read more
Why would my pediatrician be concerned about my 15 month (13 adjusted) identical twins girl's height?
We always watch it: Pediatricians always watch the height, weight, and head size for a baby or toddler. That's how we know if the growth is fine. Sometimes, two or three measurements are needed to get an accurate number on a squirming baby. We get concerned if a number is "off the graph" on the growth chart, or if numbers are trending too high or low for a particular child compared with her peers, sibs, or parents. ...Read moreSee 1 more doctor answer
Identical twins have the same DNA sequence, then how would you explain the different patches of sweat glands, can you explain?
The twins share the same DNA sequence but going from a fertilized egg to splitting into multiple cells to form a human can be influenced by several factors that can lead to individual differences. I found this article very helpful in answering your question.

Not always: They would be no more likely to look alike than any other siblings. ...Read more
If you are asking: If two identical twins, say both are women giving birth at the same time, have a higher chance of having the same gender for their babies, then the answer is no. The probability is 50% for 1 twin mother and 50% for the other twin mother delivering both a boy, 0.5 x 0.5 = 0.25 or 25%, but adding to the same probability for a girl. So 25% both girls + 25% both boys = 50%. ...Read moreSee 1 more doctor answer
