Fraternal means "brother-like." Identical twins result from a single fertilzed egg dividing into two separate embryos so the twins share all DNA. Fraternal twins result from two different eggs being fertilized by two different sperm at the same time. The babies are then born at the same time, but only share 25%of their DNA with each other, which is the same amount that siblings born at different times share. The word fraternal used in social organizations, like "the fraternal order of"...refers to the thought that the members are like brothers to each other. Modern french uses the word frere to mean brother.

actualy, furturnal twins are normal. identical twins are rare. identical twins are twins that look axactly alike, and furturnal twins do not look the same.

∙ 9y agoFraternal twins are different than other twins because they can be different genders. They also do not look just like one another. They are just like any brother and/or sister except that they born at the same time.

∙ 12y agoThere are two types of twins; fraternal and identical. Identical twins result from a single fertile egg splitting to produce two identical individuals. Fraternal twins simply mean that two eggs entered the womb and were simultaneously fertilized. This results in non-identical individuals who are about as similar as ordinary siblings.

Can twins be two different races?
Of course; identical twins are fertilized from the same sperm and egg, whereas fraternal twins are fertilized from different sperm and egg; thus, fraternal twins would resemble each other no more than regular siblings born at different times.
Is it more likey for a fraternal twin to give birth to a set of fraternal twins than to just one baby?
The same as anyone else, unless his partner has a history of twins in her family. Twins are a result of the ovum (egg) splitting after fertilisation (identical twins), or the release of two eggs during ovulation (fraternal twins). It has no bearing on the male contribution to fertilisation (being the sperm).
Is the DNA in twins the same?
if they share 1 heart then yes they do. but if they have different hearts then they do not
Are identical twins developed from one egg or two?
There are at least three ways to produce twins. One is when the female produces two eggs, both of which are fertilized by the male. This is how fraternal twins are produced. Fraternal twins can be both the same sex or different sexes. Fraternal twins may only bear a slight resemblance to one another, no more than any two siblings might. (Fraternal twins can actually have different biological fathers, because the eggs may be produced a day or two apart.) Another is for the woman to produce one egg which is fertilized by the male, and then the egg divides into two. This is the traditional way that so-called identical twins are produced. Identical twins are always the same sex. (I use the term 'so-called,' because they are actually 'mirror image' twins.) A third way is for the woman to produce one egg, which then divides into two, which are both subsequently fertilized. There is a greater chance that such twins will resemble one another than fraternal twins, and they may be the same or opposite sexes.
Non-identical twins are called?
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
Can twins be two different races?
Of course; identical twins are fertilized from the same sperm and egg, whereas fraternal twins are fertilized from different sperm and egg; thus, fraternal twins would resemble each other no more than regular siblings born at different times.
Is identical twins are more closely related than tyhe fraternal twins?
Yes. Identical twins started out as one egg and one sperm cell and are genetically identical. Fraternal twins come from two eggs and two sperm cells and are no more closely related than any other sibling.
True or false fraternal twins are more closely related to each other than to other children in a family?
false
Why might genetically identical twins have different phenotype?
This is because fraternal twins are simply two full siblings that happen to share the womb at the same time. There is no more reason for fraternal twins to be the same than there is for any brother/sister, brother/brother or sister/sister sibling set to be the same.
Why do you think identical twins were more alike than fraternal twins?
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
Are fraternal twin calves infertile?
It doesn't work that way. A heifer calf is only infertile if she is twinned with a bull calf and if her and that bull calf share the same placental tissues. In most cases such twins are fraternal, but simply stating that fraternal twins versus maternal twins are more prone to infertility than the other is stating falsehoods.
What are the odds of having twins twice?
From what i know, if your twins are identical then you have no increased chance of having twins a second time. If your twins are fraternal, you are twice as likely to have twins again because fraternal twins are the result of more than egg being released and that is a genetic trate.
Do Identical twins think more alike than Fraternal?
Yes. Fraternal twins don't look alike at all. Identical, meaning to look the same, are well, identical.
Is it more likey for a fraternal twin to give birth to a set of fraternal twins than to just one baby?
The same as anyone else, unless his partner has a history of twins in her family. Twins are a result of the ovum (egg) splitting after fertilisation (identical twins), or the release of two eggs during ovulation (fraternal twins). It has no bearing on the male contribution to fertilisation (being the sperm).
Mike and mack are identical twins while betty and bonnie are fraternal twins if mike is affected by schizophrenia then which of following statements is most likely true?
Mack has a 49% better chance of developing the disease than the fraternal twins
What is the probability of having twins if your dad is a fraternal twin and you are a identical twin and your moms dad is a fraternal twin?
The probability is the same as if you had no history of twins in your family. There is no genetic component with identical twins, it is just something that happens. Fraternal twins occur if a mother "drops" two eggs in one month. Your father being a fraternal twin does not make you "drop" more than one egg in a month and so does not increase your chances of having twins. Your maternal grandfather being a fraternal twin did not effect your mother's ability to drop more than one egg and so did not effect your ability to "drop" more than one egg and so does not increase your ability to have twins.
