What are the chances of identical twins?
the chances of having identical twins are about 1 in 300.
What percentage of twins are fraternal?
There is no precise percentage of fraternal or identical twins but it is estimated that 2/3 of all twins are fraternal where as 1/3 of twins are identical.
What is the probability of having twins if your dad is a twin?
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.
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.
If the probability of getting identical is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen at random will not be a twin?
1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Why identical twins are similar?
If they were not then they would not be called identical twins!
What percentage of twins are identical?
Approximately 30 of twins are identical, also known as monozygotic twins.
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
How are twins identical?
Twins are identical because they come from the same egg.
How do you get identical and non identical twins?
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
If I had identical twins 3 years ago what are my changes of having another set of identical twins?
The same as when you had the first set of identical twins.
A zygote that separates into two clusters of cells insted of just one prduce?
Non identical twins.
What are the chances of identical twins?
the chances of having identical twins are about 1 in 300.
Do identical twins always share a placenta?
No, identical twins do not always share a placenta. In some cases, identical twins may have separate placentas.
Why are the twins identical?
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
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.
