Fraternal twins come from the fertilization of two different eggs. It can cause them to look almost the same, but they could just as easily be totally different, even different genders. Identical twins come from the splitting of only one fertilized egg, making them look exactly the same and they will always be the same gender.

What is the different of identical twin and flaternal twin?
Identical twins come from a single fertilized egg that splits into two embryos, while fraternal twins come from two separate eggs fertilized by two different sperm. Identical twins share 100% of their DNA, making them genetically identical, while fraternal twins share about 50% of their DNA, like regular siblings.
What is the difference in the expression of schizophrenia in identical twins attributed to?
The difference in the expression of schizophrenia in identical twins is attributed to a combination of genetic and environmental factors. While identical twins share the same genetic makeup, environmental influences such as stress, trauma, or drug use can lead to differences in the onset and severity of schizophrenia symptoms between twins.
Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
How do you know if two twins are identical or just fraternal twins that look a lot alike?
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
How do twins look exactly alike?
They do look different! Even identical twins, with identical DNA, are different. Most have a slight difference in height and weight. Many people have a difficult time telling them apart because they are focusing on the wrong things. If someone looks only at the hair, they may not see that their faces are slightly different.
What is the different of identical twin and flaternal twin?
Identical twins come from a single fertilized egg that splits into two embryos, while fraternal twins come from two separate eggs fertilized by two different sperm. Identical twins share 100% of their DNA, making them genetically identical, while fraternal twins share about 50% of their DNA, like regular siblings.
What is the difference between idetical and non idetical twins in the way they are found?
The difference between Identical and Non-Identical twins is that Identical twins share the same placenta and are basically identical to one another. Non-Identical twins do not share the same placenta in the womb and two eggs fertilized at time of conception as opposed to one egg splitting in the case of Identical twins. I think that covers the basics. Hope this has clarified things for you.
What is the difference between a fraternal twins and identical twins?
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
What is the difference in the expression of schizophrenia in identical twins attributed to?
The difference in the expression of schizophrenia in identical twins is attributed to a combination of genetic and environmental factors. While identical twins share the same genetic makeup, environmental influences such as stress, trauma, or drug use can lead to differences in the onset and severity of schizophrenia symptoms between twins.
What is the difference fraternal and identical twins?
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
What is the different between identical twins and franternal twins?
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
What is the diffence between identical twins and fraternal twins?
Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.
When was Canada's first successful kidney transplant between identical twins performed?
Canada's first successful kidney transplant between identical twins was in 1958.
What describes similarities between identical twins?

What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
How many chromosomes do identical human twins have?
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
What name of the graft between identical twins?
the name of a graft between identical twins is called an isograft transplant, when the tissue or organ is prelevated from a donor genetically very close to the receiver, like an identical twin. Immunologically, it is closer to an autograft transplant, and some specialists even consider it an autograft transplant.
