do identical twins have the same epigenome?
529931
This study shows that, at the epigenetic level, identical twins are more similar to each other than previously recognized. ... “For decades, researchers have studied genetically identical twins to estimate what proportion of disease risk is determined by one's genes.

They're called identical twins because their genomes are identical. But even though all of their DNA is the same, they clearly are not. ... DNA and RNA sequencing technologies have advanced to the point where allele-specific expression can now be quantified.

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. ... However, in the case of identical twins, early in development, this embryo divides into two. This creates two babies rather than one.

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.

Yes! 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.

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.

Despite having the same genetic makeup, identical twins have their own distinctive personalities. ... Importantly, identical twins raised in the same household — the same "outer" environment — still develop personality differences over time.

The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births. And while it may be obvious, identical twins are always the same sex, either both boys or both girls, at birth. Why? Well, they don't just look alike — they also share the exact same DNA.

We get 50% of our DNA from each parent, so only identical twins have the exact same DNA. So unless you're an identical twin, your AncestryDNA® test results will likely be different to your sibling.

Identical twins share the same genotype, since their genomes are identical; but they never have the same phenotype, although their phenotypes may be very similar. ... A phenotype is said to be canalized if mutations (changes in the genome) do not noticeably affect the physical properties of the organism.

Identical twins share the same genotype, since their genomes are identical; but they never have the same phenotype, although their phenotypes may be very similar. ... The concept of phenotypic plasticity defines the degree to which an organism's phenotype is determined by its genotype.

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. ... For example, we know that identical twins can be different heights.

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.

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.

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 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).

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