are identical twins always look alike?
243675
Yes! Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. But there are environmental differences that can affect the way they look and behave. ... As identical twins get older they may look more and more different, because they are exposed to more diverse environments.

-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.

In case you don't see the differences between the twins above, or you don't believe that identical twins are not truly identical, it has been proven time and again that monozygotic twins have variations in their DNA sequences, their fingerprints are different, their weight and height can differ, their facial features ...

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.)

Despite having the same genetic makeup, identical twins have their own distinctive personalities. Just how their individuality emerges has remained a bit of a mystery. ... Importantly, identical twins raised in the same household — the same "outer" environment — still develop personality differences over time.

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.

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.

Identical twins share a lot of similarities in both their genetic makeup and their physical appearances. But, like those who aren't twins, identical twins all have unique fingerprints.

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.

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?

We think of identical twins as having identical DNA. And they also each use their DNA a bit differently too. ... 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.

Identical twins do not have identical DNA. It is very very close, because they do start out from the same point, but as they develop in the womb, very tiny differences will appear due to the influence of hormones and mutations.

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. ... While this rarely happens, it makes it so that one identical twin may have a genetic condition, while the other twin does not.

Identical Twins Are Genetically Different, Research Suggests. SAN FRANCISCO – Identical twins may not be so identical after all. ... While past studies have looked at genetic changes, or mutations, in sperm and eggs, which can be passed on to offspring, very few studies have looked at somatic mutations.

Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. ... So identical twins with identical DNA may have different genes turned on, causing them to look and act differently, and even to develop different diseases such as cancer.
