Fraternal twins are more popular.
No, about 1 in every 3 twins is an identical twin. Source: http://twins.usc.edu/about.htm
i say that identical twins are the least rare because like me a fraternal twin i only know 1 pair of fraternal twin.
Identical twins do not have the same DNA; it is quite similar, but not exact. fraternal twins are no more similar than sibling likenesses.
Yes. Fraternal twins don't look alike at all. Identical, meaning to look the same, are well, identical.
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.
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.
Not necessarily. "Same sex fraternal" twins are more common than many people realize.
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex
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.
theres no way to make yourself have twins. that happens when two eggs are released when you ovulate fraternal) or the egg splits in two (identical). twins are more common if they run in your family
Identical twins are a single fertilized egg that divided itself into 2 embryos. fraternal twins are 2 separately fertilized eggs.
Yes. Fraternal twins are no more like genetically than any other sibling combo, while identical twins will have very, very close to the same DNA.
There 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. See related link to Wikipedia for more details.
Fraternal twins come from separate eggs and are no more alike than regular siblings while identical twins come from the same egg splitting into two and have identical DNA.
it was 1/250 just for twins, but identical is more common then futurnal
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.
Yes, it is possible. It would be more common if the twins are fraternal that only one twin would be affected by the disease because it is a recessive trait, meaning both parents must be a carrier for the offspring to be affected. If the twins are identical and the tay-sachs gene is present, then boths twins will be infected because identical twins have identical DNA
if twins run in the family u are more likely to have twins but most likely fraternal because identical twins are just a very unique coincidence
Monozygotic (Identical or Maternal) twins are identical because they came from the same egg and were split after conception but before fetal development. Identical twins have nearly identical DNA, however, environmental factors may switch genes on and off, differences are more pronounced as the twins age. Dizygotic (Fraternal) twins are not identical. They are as different as any other siblings.
There are two types of twins, identical and fraternal. Identical twins come about by the splitting of a zygote (fertilised egg) at some stage. This is completely random and the incidence is the same in all races. My husband and his borther are identical twins. Fraternal twins are produced when two eggs are fertilised by two sperm in the same menstrual cyle. They may be of the same sex or opposite sexes and are no more alike that any other brothrs and sisters. Fraternal twins are more common in older, well-nourished, fertile women (or if two embryos are implanted after IVF) and vary between races. Some African peoples have a very high rate of fraternal twinning with far Eastern races having the lowest rate. Two of my children are fraternal twins. Photographs on my Bio page englishangel
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.
There are two primary types of twins, Identical and Fraternal. Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins. Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
Luck. There is no way of making someone have identical twins. There are two primary types of twins, Identical and Fraternal. Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins. Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older. Fertility drugs also make this more likely to happen.
I'm not sure on the actual percentages. It firstly depends on if your father is an identical or non-identical twin. (Maternal or fraternal) Non-identical (fraternal) twins are the hereditary type, not the identical ones. Identical twins are simply a hiccup with the cell division during fetal growth, whereas non-identical twins are due to the hereditary tendency of the woman releasing more than one egg at a time. The gene for non-identical twins is directly passed from fathers to daughters, and the chance of having twins usually skips a generation too (like baldness in men!). So, if your father is a twin (a non-identical twin) and you are his daughter, it's possible that you may also have twins, but it's far more likely that your daughter will. My father is a twin (his brother died at birth and it's not known if he was maternal or fraternal unfortunately) and I only have 1 child (a daughter). She has a very high chance of having twins if dad was fraternal.
Not usually no. Fraternal twins are conceived from separate eggs within the mothers womb. While identical twins start as one embryo and then split and grow into 2 babies. If a woman was sexually active with more than one man it is possible for fraternal twins to have different fathers, but it is extraordinarily rare.
