does identical twins look alike?

After all, while huge differences can and do happen with fraternal twins, identical twins are usually exactly that -- identical in skin, hair and eye color. ... Even though this is true for all identical twins, we can't usually tell because the changes happen in parts of the DNA that don't affect how identical twins look.

Even identical twins brought up in similar environments won't really be identical. They won't have the same fingerprints. They'll have different freckles and moles.

However most identical twins grow up together and not only share the same genetics, but also the some environmental influences. ... My twin sister and I have almost always weighed the same or very, very close to the same.

7.1 Two identical twins have exactly the same set of genes. They are separated at birth and grow up in different households. If a scientist were to study the twins as adults, would he find them to be identical in every way, since they have the same genes?

The team concluded that the chances of someone looking exactly like someone else in all eight features is about one in 1 trillion. Which means that there's definitely a mathematical chance for two doppelgängers to exist, but it's highly unlikely.

After all, while huge differences can and do happen with fraternal twins, identical twins are usually exactly that -- identical in skin, hair and eye color. But, actually, twins who start out with identical DNA always have slightly different DNA by the time they're born.

Can fraternal twins look so similar that they are mistaken for identical? Yes, it is possible for same-sex fraternal twins to look extremely similar. Like any siblings, fraternal twins are the products of two separately fertilized eggs from the same mother and father.

Identical twins will have the same eye color. There are a few genes involved in eye color, and their genes are identical. It is possible for environmental factors after birth (epigenomics) to cause differences in the expression of genes, and therefore giving each twin a different phenotype (or trait).

Scientists have shown that identical twins have very similar marks when they are born. But, as they age, the marks in their DNA become more and more different. So even though identical twins have the same DNA, they are using it in different ways. ... Both the right and left side of your face were made using the same DNA.

-The identical twins will have similar physical structures according to same genes. But they will have different habits, behaviors, characters, personalities, interests, intelligences and thinking processes, etc. because those traits are not determined by genes. So identical twins will not think alike.

Are identical twins 100% genetically identical? It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother. (In contrast, fraternal twins are formed from two different sperm and two different eggs.)

look-alike. A look-alike is someone who looks almost exactly like another person. Running into your look-alike in a big city would be quite shocking. Some look-alikes are related, like identical twins or cousins who resemble each other to an uncanny degree.

They come from the same fertilized egg and share the same genetic blueprint. To a standard DNA test, they are indistinguishable. But any forensics expert will tell you that there is at least one surefire way to tell them apart: identical twins do not have matching fingerprints.

Because with the division of DNA, each identical twin may be offered with different genes that can influence a lot of physical features. So, it is not something to worry about if you have twins who look the same but have different skin colors or hair quality, or eye color or anything like that, it is quite normal.
603673
Identical twins have the same DNA as each other, but different from their parents. A clone, however, only has one parent and has exactly the same DNA as that parent.
724477
Things like your eye and hair color are controlled by your DNA. This is why identical twins look so much alike -- they share the same DNA. And yet, they aren't exactly alike. ... Identical twins have physical differences because when it comes to the way you look, both nature and nurture matter.

Are Dylan and Cole Sprouse identical twins? Yes, they are identical twins. While most people might think that identical twins have to look alike in order to be considered as such, looks have nothing to do with whether or not they are considered as such.
