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.

∙ 12y agoIdentical twins start as one egg and one sperm, and when the first cell division occurs, each new cell becomes a separate being with identical DNA (genetic makeup).
Fraternal twins form from two eggs and two sperm, each fertilized within the same cycle and implanting in the uterus at or close to the same time. They are genetically different, like siblings, but occupy the uterus at the same time and are born one right after the other (usually).

What is the different of identical twin and flaternal twin?
IDENTICAL TWINS splash from 1 fertilized egg and flaternal twins splash from 2 fretilized eggs.identical twins have same DNA while flaternal twins do not have same DNA.
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.
What is the difference in the expression of schizophrenia in identical twins attributed to?
The difference is attributed to environmental factors that impact the expression of schizophrenia.
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.
Who are clones fraternal twins or identical twins?
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
What is the different of identical twin and flaternal twin?
IDENTICAL TWINS splash from 1 fertilized egg and flaternal twins splash from 2 fretilized eggs.identical twins have same DNA while flaternal twins do not have same DNA.
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 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.
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 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.
Can an infant tell the difference between its identical twin mother and aunt?
It is unlikely for an infant to tell the difference between its identical twin mother and aunt initially, as they share the same genetic makeup and may look very similar. However, over time the infant may start to recognize subtle differences in behavior, scent, or other cues that help differentiate between the two.
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.
What percent of genetic makeup is shared by identical twins?
100%Identical twins develop from the same egg, so have the same DNA. The only thing different between identical twins is finger prints, and retinal patterns.
