can identical twins have different traits?

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. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.

Both the twins have the exact same genetic potential for a particular height but they can end up having different heights depending upon external factors such as one of them is athletic while other is a couch potato. ... Identical twins would be identical in body type.

Identical twins are always the same sex; they usually are the same height, weight and have similar hair color. In relation to the genetic differences in MZ twins, different genes can be turned on or off which is why one identical twin may have a condition or disease that the other doesn't.

Identical twins have identical genes but they don't have identical brains and that is because learning leads to anatomical changes in the brain and even identical twins will have different social experiences, different learning experiences, and therefore will end up having different brains.

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.

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 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.

Even identical twins who share the same appearance and genetics do not have the same handwriting. People may copy your handwriting but they would never get to write in an identical way. Experts say our handwriting can tell a lot about us including our health and motor skills.

After all, identical twins have the same genes, share the same womb and usually experience the same childhoods. ... By comparing identical and fraternal twins and their sensitivities to illnesses, it is possible to separate the genetic roots of conditions from their environmental influences.

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.

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.

Twins can be different in appearance, having different skin colors, if they came from different eggs. When two eggs are fertilized by two different sperms then the babies will be fraternal twins and have different appearances, this is because they will have different DNA makeup and chromosomes.

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. ... The fingerprints of identical twins do look more similar than the fingerprints of non-twins. This is because your fingerprints are partially controlled by your genes.

Are identical twins allergic to the same things? A. Not necessarily, though there is a strong genetic component in allergy. Identical twins, who inherit identical genes, tend to be far more similar in their allergies than siblings or fraternal twins, who develop from two embryos, not one.

Identical twins share all of their genes, while non-identical twins, just like non-twin siblings, share half of their genes. So, we can assume that any differences in traits between identical twins come from the environment, and not from differences in their genes.

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. But now, researchers have found that life experiences affect brain development — and this may help us understand how personalities form.

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.
