can identical twins not 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.

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 ...

Although identical twins have the same genes, they don't always look the same. This is because children's health and development are shaped not only by genes but also by experiences in the womb and after birth. For example, a twin who receives less blood from a shared placenta might weigh less at birth.

Because identical twins come from a single fertilized egg that splits in two, they share virtually the same genetic code. Any differences between them—one twin having younger looking skin, for example—must be due to environmental factors such as less time spent in the sun.

Identical? No, of course not, but they can be quite close. Genetics no doubt plays a part in a person's voice but it also probably has something to do with growing up with and being close to a person. My twin sister and I have very similar voices and only people close to us can tell our talking voices apart.

Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. ... As identical twins get older they may look more and more different, because they are exposed to more diverse environments. The science of epigenetics explains how these environmental influences can affect the genes.

Because identical twins are genetically equivalent, their facial appearance is also quite similar. Generally, differences in their appearance can only be attributed to exposure to different environmental factors (such as dietary habits and aging) and rare cases of genetic mutations.

Fingerprints are completely unique to every individual person. ... So even if identical twins are genetically similar, the "pressure" faced by the fetus in the womb can affect their fingerprints. So ya, identical twins could fool everybody with their looks, but they ain't fooling the fingerprint test!

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.

Identical twins have DNA that is 99.9% the same. They also have almost nearly identical brain wave patterns. But they do have different fingerprints and teeth marks!

Because identical twins share the same genetics, you may wonder whether they have identical fingerprints. ... Identical twins do not have identical fingerprints, even though their identical genes give them very similar patterns. 1﻿ The fetus begins developing fingerprint patterns in the early weeks of pregnancy.

Myth: Clones are always identical in looks. They have the same genes, but look a little different. ... Human identical twins also have the same genes, but because those genes are expressed differently in each person, they have different freckle and fingerprint patterns.

Identical twins or triplets have the same genetic identity, are always the same sex, and look almost exactly the same. Fraternal multiples develop from separate eggs that are each fertilized by a different sperm.

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.

Just because monozygotic twins have the same DNA doesn't mean they will look identical. Different hair color in monozygotic twins can happen in two ways. ... They both still have genes for hair color from both parents, the same DNA, but the could each express the color from the other parent.

Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. ... This can mean one twin starts getting more to eat even before they are born! Another physical difference between identical twins is their fingerprints.

The bottom line. 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.
