No, faternal twins are created from two different egg cells. They have some similar genetic information however. Indentical twins on the other hand, would have identical fingerprints since they are created within one egg cell.

Are twins that can only be two girls or two boys identical?
No. In order for them to be identical they needed to start off as the same cell and divide so at first their DNA is identical meaning they have the same sex. During development slight changes may occur but the sex always stays the same. Boy-girl twins are always two different cells meaning that they are not identical. The term for boy-girl twins is furturnal. You can however have boy-boy twins and girl-girl twins that are not identical and they are also called furternal. So basically, identical twins start off as one cell that divides and furternal are two individual cells. There is polar body twinning, that's when the egg splits before fertilization, and that can cause a male and a female. This is called semi identical twins or half twins. They share 75% of their genetic markers.
Is there such thing as a chimera?
When a set of fraternal twins have offspring, it is possible for one or more of these children to contain both sets of the fraternal twins separate DNA. Testing may show one set or the other, which would create a false reading, though true. This is the result of a genetic mutation during incubation, while the twins are invitro, but because they have different DNA their genomes can merge or mix, resulting in a genetic "chimera." This is rare, but possible.
Are there two animals that look exactly the same?
people do look the same but we all have a least one characteristic that makes us different. DNA is so complex and everyones is different. so really no two people can look EXACTLY the same but they can look similar only exception is twins
Do turtles and tortoises have the same DNA?
Turtles and Tortoises have highly similar DNA, as tortoises are a subgroup of turtles.
Is DNA testing different between different species?
DNA testing is the same, no matter what species it is performed on. DNA testing can be used to find genetic abnormalities and establish biological connections.
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
Do twins have the same DNA?
identical twins do. just not the same fingerprints.
Is the DNA in twins the same?
if they share 1 heart then yes they do. but if they have different hearts then they do not
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
A couple has twins. One is a boy and one is a girl. How do you know what kind of twins they are?
they are fraternal twins because they do not have the same dna
Who are clones fraternal twins or identical twins?
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
Why is DNA sometimes called the fingerprint inside your body?
because everyone has different DNA and different fingerprints.
Why do you think identical twins were more alike than fraternal twins?
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
Why don't twins have the same prints?
No one has the same fingerprints. That's just the way of genetics. Identical twins look exactly the like, but their DNA isn't the same.
Do siblings have similar fingerprints?
Depends. If they are twins (Identical) then yes. There has been reports of Identical Twins having same DNA and Finger prints. There has never been any records of regular siblings sharing the same fingerprints
Why are identical twins identical and fraternal twins are not?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
What effect does heredity have on fingerprint characteristics?
DNA does not affect fingerprints. Identical twins- people with the exact same DNA- have different fingerprints. Fingerprints (and toe, lip, or any other -print your body has) form in the womb at random.
