can identical twins be different skin colors?

Explaining the phenomenon Dr Claire Steves from the Department of Twin Research, said that multiple genes control skin colour and while identical twins are very likely to share them completely, it is not guaranteed.

5﻿ Monozygotic (identical) twins will have the same blood type, with a few very rare exceptions. Dizygotic (fraternal) twins may have the same blood type, or they may have different types. ... However, twins with the same blood type can be either fraternal or identical.

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.

Blood type is entirely determined by DNA, so identical twins pretty much always have the same blood type. But because of the small changes in DNA that can happen in the womb, it's entirely possible for twins to have different blood types from each other.

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!

Although identical twins do share the same DNA. In that respect, they are the same person.

At first blush it might seem impossible they could look so different. 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.

It's not possible. Identical twins are completely identical. That's why DNA tests can't tell which twin is which. As their DNA are completely identical, their natural hair color will always be the same.

Do identical twins have identical fingerprints? No! ... MZ twins share the same genetic makeup (DNA) because they are formed from a single zygote (fertilized egg). However, fingerprints are not an entirely genetic characteristic.

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.

Yes! 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.

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 ...

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.

Mixed twins are fraternal twins born to multiracial families which differ in skin color and other traits considered to be racial features. ... In such cases, fraternal twins can differ from each other quite dramatically in terms of skin color or other physical characteristics.

Mirror image: Identical twins are believed to be genetically identical, but one twin can have mutations not shared by the other. Identical twins can be genetically different, which could explain why they do not always share disorders such as schizophrenia or autism, according to a study published in March in PLoS One.

It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not.

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.
