Fraternal twins (or nonidentical twins) develop when two separate sperm fertilize two separate eggs. This creates two genetically different (dizygotic) embryos. In this case, the only thing the babies will be sharing (for now) is your uterus (give them some credit — it’s not that big!).
What else can I help you with?
What if one identical twin is diagnosed as schizophrenic there is a high probability that the other twin will also have this mental disturbance?
Identical twins share 100% of their genetic material, so if one twin has schizophrenia, the other twin has a high likelihood of developing it due to genetic predisposition. However, environmental factors also play a role in the development of schizophrenia, so it is not guaranteed that both twins will develop the disorder.
What is a phantom twin?
A phantom twin refers to a phenomenon where one twin in a multiple pregnancy does not survive, but the other twin continues to develop. The surviving twin may experience sensations or emotional connections related to the deceased sibling, which can include feelings of loss or even physical sensations. This concept can also extend to cases where a partial or fully formed twin is absorbed by the other during early pregnancy, leaving the surviving twin with physical anomalies or psychological effects related to their phantom sibling.
Is it possible that the mother was pregnant with twins and one grew in the unborn baby?
Yes, it is possible for a mother to be pregnant with twins, where one twin can develop inside the other. This phenomenon is known as "twin-to-twin transfusion syndrome" or "vanishing twin syndrome," where one embryo is absorbed by the other during early pregnancy. In rare cases, a condition called "fetus in fetu" can occur, where a malformed twin becomes encapsulated within the other twin's body, resembling a parasitic twin. However, such cases are extremely uncommon.
Who is the older one between the first twin and the second twin in conception?
The first twin conceived is typically considered the older one, as twins develop from the same pregnancy. In cases of identical twins, one may be born slightly before the other due to timing during labor, but in terms of conception, the first twin is always regarded as the older sibling.
Can one twin hide behind the other in gestation?
In gestation, one twin cannot physically "hide" behind the other in a way that would obscure its existence entirely, as both embryos develop in the same amniotic sac (in the case of identical twins) or separate sacs (in fraternal twins). However, one twin may be smaller or less developed than the other, which can sometimes lead to difficulties in imaging or assessing the smaller twin during ultrasounds. This phenomenon is often referred to as "vanishing twin syndrome," where one twin is absorbed into the other or the surrounding tissue. Overall, while one twin might be less visible, both are present and developing.
Is it possible for only one twin to develop autism?
Yes, it is possible. In one study, the chance that an identical twin has autism when the other does is 82%. That means that 18% of the identical twins did not have autism. It is much more likely that an identical twin will have autism if the other does than that a fraternal twin or other sibling will, but it does not happen every time.
Can you miscarry only 1 of fraternal twins?
Yes, it is possible to miscarry one of fraternal twins while the other continues to develop. This phenomenon is known as selective reduction or "vanishing twin syndrome." It can occur early in the pregnancy, where one twin is lost and the body absorbs the tissue, or it can happen later, but the surviving twin typically continues to grow and has a chance of being born healthy.

What is gemellology?
I searched this in google:A twin is one of two offspring produced in the same pregnancy. Twins can either be monozygotic, meaning that they develop from one zygote that splits and forms two embryos, or dizygotic, meaning that they develop from two eggs, each fertilized by separate sperm cells.That is gemellology.
Where is the Twin Groves Branch Library in Twin Groves located?
The address of the Twin Groves Branch Library is: 10 Twin Groves, Twin Groves, 72039 M
Why would one identical twin develop Parkinson Disease and not the other?
Parkinson's disease is not only genetic but another factor that could cause Parkinson's disease would be environmental issues. If one twin is more exposed to certain toxins in the air like pesticides, they could be more likely to get Parkinson's Disease.
