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.
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
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.
Do turtles and tortoises have the same DNA?
Turtles and Tortoises have highly similar DNA, as tortoises are a subgroup of turtles.
How do birds and dogs both use DNA?
Same as you do : it's the coding for making proteins.
Do twins have the same DNA?
identical twins do. just not the same fingerprints.
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
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
Do identical twins have the same finger prints and DNA at all?
Yes they do because they are created from the same egg when it splits so they will have the same DNA because they are identical but on the other side regular twins don't have the same DNA because they are from diffrent egg and sperm
Do twins have different fingerprints?
Yes, twins have different fingerprints. Even identical twins, who share the same DNA, have unique fingerprints because fingerprints are formed randomly in the womb due to factors like pressure and environment.
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.
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.
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.
Do identical twins have the same fingerprints is it a testable question?
No, identical twins do not have the same fingerprints. While they share the same DNA, fingerprint patterns are influenced by both genetic and environmental factors during fetal development. This makes it a testable question, as researchers can compare the fingerprints of identical twins to assess their similarities and differences. Studies have consistently shown that even identical twins have unique fingerprints.
Who has DNA fingerprints that are similar to your DNA fingerprints?
No two individuals (except identical twins) have the same DNA fingerprints, as they are unique to each person. DNA fingerprints are also known as DNA profiles and are widely used in forensics and paternity testing because of their individuality.
If your a twin do you have the same finger prints?
No you do not have the same print as your twin. Every single human being on Earth has a different print. But it is good to have different fingerprints. That's how some people can tell twins apart. No twins or anybody for that matter have the same prints. But identical twins do have the same DNA ( doxyribo Nucleic Acid )
