how do identical twins have different personalities?

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. ... Genetics play a huge role, but so does the environment, which can influence the way our genes are expressed.

There are two types of twins – identical (monozygotic) and fraternal (dizygotic). To form identical twins, one fertilised egg (ovum) splits and develops two babies with exactly the same genetic information.

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 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.

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.

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.

Identical (monozygotic) twins happen when a single egg (zygote) is fertilised. The egg then divides in 2, creating identical twins who share the same genes. Identical twins are always the same sex, so if your twins are identical, you'll have 2 girls or 2 boys.

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 high level of plasticity means that environmental factors have a strong influence on the particular phenotype that develops.

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. ... Usually, the egg and sperm come together and create an embryo, which eventually grows into a human baby.

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.

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 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.

Because with the division of DNA, each identical twin may be offered with different genes that can influence a lot of physical features. So, it is not something to worry about if you have twins who look the same but have different skin colors or hair quality, or eye color or anything like that, it is quite normal.

Identical twins start out as genetically identical: they have the same alleles. They are formed by a fertilised egg dividing into two separate individuals. They are always of the same sex, and are monozygotic or MZ twins (mono = one; zygote = fertilised egg). ... Fraternal twins are twice as common.

In my opinion, identical twins are not likely to be psychopaths if one of them is a psychopath. ... But they will have different characters, personalities, intelligences and thinking processes (and also psychopath trait) because those traits are not determined by genes.

Indeed, it is extremely rare to find genetically identical twins, who differ in body weight (demonstarting just how highly heritable body weight actually is). Thus, body weight in identical twins is remarkably homogeneous not only because of the heritability of weight per se but also due to heritability of weight gain.

-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.
