Can identical twins have twins with someone who is not identical?
They have as much chance of having twins as anyone else, regardless of who their partner is.
If atleast one person in your family has identical twins what are your chances of having identical twins and does someone in your family have to have had twins for you to be able to have twins?
The chance of having non-identical twins can run through genetics or be affected by the age of the mother. So the more people in your family tree that have twins, the more likely you are to have twins. However, twins can occur by chance, to someone who's family tree has no cases of twins, or from IVF. You do not have to have twins in your family line to give birth to twins. The chance…
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.
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…
Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
