Are female twins that are not identical called Fraternal or Maternal?
Female twins that are not identical are called fraternal twins. Fraternal twins occur when two separate eggs are fertilized by two separate sperm. Maternal twins refer to twins that share the same mother but can include both identical and fraternal twins.
Do identical twins have identical brains?
No they do not. Identical twins have identical DNA structure, and therefore they have very similar cell structure, leading them to have vastly similar organs (same size, health issues, etc.). However, everyone, even identical twins, do not share the exact same organs. Some identical twins get migraines, while the other doesn't. In some cases, one twin will be homosexual and the other heterosexual. In any case, by nature, identical twins do not have identical brains, and by nurture they experience different things, learn different things, and process information in different ways, resulting in the twins having differing opinions, etc. No two brains are exactly alike.
Do identical twins with opposite genders exist?
Yes, it's possible for a mutation in the chromosome to produce otherwise-identical twins with opposite genders. But generally no, identical twins have the same gender. (but fraternal twins have different genders just as often as any siblings)
Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
If twins aren't identical what are they called?
Twins who are of the opposite sex or do not look alike are fraternal twins ~ not identical. This means that at the time of their conception ~ two eggs were fertilised. In the case od identical twins, one egg is fertilised and split in half.
Do conjoined twins have the same sex?
Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.
Is the DNA from identical twins identical What about fingerprints?
There are differences in both DNA and fingerprints.The Claim: Identical Twins Have Identical DNA
What are the chances of having twins after aborting twins?
It is the same for any other pregnancy. Abortion does not change the randomness of identical twins or the familiar tendency to have fraternal twins.
Are the Bella twins identical twins?
No, they are ferternal. They have different colored eyes and one used to be shorter then the other. If you get any of their old movies you can tell. Mary-Kate usually has shorter hair then ashley, but that doesn't make them ferternal.
What are the differences between identical twins?
Identical twins are genetically identical, meaning they share the same DNA. However, differences can arise due to environmental factors, epigenetic changes, and random mutations that occur during development. These factors can lead to variations in appearance, personality, health outcomes, and other traits between identical twins.
Is identical twins are more closely related than tyhe fraternal twins?
Yes. Identical twins started out as one egg and one sperm cell and are genetically identical. Fraternal twins come from two eggs and two sperm cells and are no more closely related than any other sibling.
Is the DNA in twins the same?
Twins can have very similar DNA, especially in identical twins who come from a single fertilized egg that splits into two. On the other hand, fraternal twins are no more similar genetically than any other siblings. Some slight genetic differences can arise due to mutations that happen after the initial egg fertilization.
