Yes. If a woman has been sexually active with more than one person in a short period of time, there is a less than a one percent chance that a mother will have fraternal twins by two different fathers.
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.
It's very, very, very, very unlikely, but it is possible. It's called heteropaternal superfecundation. Here's a link about it: http://en.wikipedia.org/wiki/Superfecundation
Yes, it is entirely possible. Cats often end up having litters with more than one father between them; the same is rarer in humans but has still been known to occur.
Yes, it is possible and has happened, though there have only been a couple of documented instances of it.
no,twins are supposed to have same parents because then they will be cousins
Nonidentical twins Dizygotic twins (commonly known as fraternal twins, but also referred to as non-identical twins or biovular twins)
In Greek mythology, Castor and Pollux were twins with different fathers, and were brothers of Helen of Troy.
Identical twins will have the same father, so a paternity test is done just like for any kid. With fraternal twins, it is possible, but very, very rare, to have different fathers for the babies.
Yes, twins can be of different skin colours. However, they could not be identical twins.
No, even though twins do have identical DNA, they can have far different environments and life experiences. So, two identical twins though genetically the same could be very dissimilar in intelligence.
There is Identical twins, Nonidentical twins and Conjoined twins.

10 million identical and 115 nonidentical.
Non-identical twins occur when the mother ovulates and two separate eggs are released and fertilised. This is different to identical twins, they occur when one original egg splits n two and develops in tandem. then yo have sex
No, most pregnancies do not start out as twins. When the ovaries release two eggs and both are fertilized then will twins be born (fraternal/nonidentical twins). Or a fertilized egg may divide before implantation resulting in identical twins.
The reason why some twins are identical and some are not starts in utero. Identical twins occur when one egg is fertilized and it splits to create two embryos. Nonidentical twins come from different fertilized eggs.
In Greek mythology, Castor and Pollux were twins with different fathers, and were brothers of Helen of Troy.
Non-identical twins happen when two eggs are fertilized at the same time. This happens when the mother ovulates twice, so she has two separate eggs that can be fertilized and develop into fetuses.
Fraternal twins (or nonidentical twins) develop when two separate sperm fertilize two separate eggs. This creates two genetically different (dizygotic) embryos. In this case, the only thing the babies will be sharing (for now) is your uterus (give them some credit — it’s not that big!).
A Croatian woman who slept with two men at the same time has given birth to twins with two different fathers. The 23-year-old student, who has been named only as M B, gave birth to non-identical twins in Zagreb seven months ago. However, she has revealed that DNA testing has shown the children have different fathers.She told daily Jutarnji List, "I was shocked at getting pregnant and even more surprised when doctors told me that my two sons had different fathers." Doctors have said twins being born to different fathers is extremely rare.
