Could twins come from the father / man is different?

There are twins who came from an egg cell There is also a twin because it's from 2 different eggs. This means that 2 cells produced female eggs, both fertilized. 1 egg = 1 cell must be fertilized by sperm. The question: Could two active egg, fertilized by different sperm (from different people) Because 2 of the fertilized egg cells of different sperm. What if the sperm of a person can only be one egg cell, while others wasted, then there is more sperm from different men fertilize an egg cell another. Is it possible? If there is a reference please include ... to be more accurate.

Just to confirm I understand your question correctly, you're asking if it is possible for a pair of twins to have the same mother but different fathers, correct? There is such a thing. It's called heteropaternal superfecundation, in which two ova are fertilised by sperm from two different men. There's a better explanation on Wikipedia here: http://en.wikipedia.org/wiki/Superfecundation#Heteropaternal_superfecundation

Wow, i never though this could be possible but since you say there is such a case then i think i should believe it. But what kind of a woman would have allowed such thing to happen? I can just imagine, a woman sleeping with two man at exactly the same time to have produced twins with different fathers. I think it won't be possible if the time interval is far from each other. I think it should be almost at the exact same time. So this kind of situation is kind of strange for me.

Twins who come from different eggs (2 eggs fertilized directly) do exist .. but the possibility is very small ... and the comparison is only 1:1000 women .... and twins from different eggs produced this baby is much different at all (the resemblance is only a little) even seem like non-twin.

Hi gengeni, It is possible for two egg cells to be fertilized by two different sperm cells if the female is willing to be penetrated by two different males. I always see it happen but I still have to see a twin out of that unique union. Interesting situation really. How are the twins related then? Half blood, definitely. But who is to determine it? What if they met another of their sibling from another mother but of the same father? What if they are twins too? Someone must be hard at work here.
