genetically they will be brothers and sisters instead of cousins.
But of course when you say twins, you really mean identical twins.

It depends on whether or not the Mom is a fraternal twin or an identical twin. If she's a fraternal twin, her chance of conceiving twins is increased, but if she's an identical twin, her chances are the same as everyone else's because, identical twins are a completely random occurence... only fraternal twinning is hereditary. And, it doesn't matter if the father is a twin or not, since it all has to do with the egg(s) :-)

First of all, identical twins are NOT genetic whatsoever. Identical twins result when a fertilized egg divides in half. The babies have the exact dna. It is a coincidence and has nothing to do with genes.
Fraternal twins are only genetic on the maternal (mother's side). Fraternal twins result when a woman ovulates and releases two eggs and both of them become fertilized and implant. Fraternal twins can also be a result of fertility treatments, since they can result in multiple dominant follicles.

Not likely. Two things cause twins. Fraternal twins are caused by there being two ova in the fallopian tubes that get fertilized. Identical twins occur when an already fertilized egg splits into two. What you are asking is weather or not there is a gene that makes you a twin, and if there were would this gene be a dominant one. (For instance, the gene that causes brown eyes is dominant over the one that causes blue.) I don’t really think the two are related.

Very rare chance. With the different genes present in each body. One could have a twin with blond hair, blue eyes, the other a red head with green eyes. There is basically an infinitive combination that can combine if they were to have kids.
It all has to do with genes. Think biology class Snapdragons the red, pink and white flowers., if a dominate or recessive trait is present , etc, etc.

No. because even in spite of the reality that the father and mom (the first set of twins, infant) became similar, it truly is conceivable that they were given different undominant genes. even as the girls undominant genes experience the mans undominant genes it truly is going to create a dominant one (that signifies that the single male might want to have created a somewhat different function from the different male's babies.)

Depends what sort of twins they are.
Fraternal twins (non-identical) are genetically predisposed - "there are twins in the family"; Identical twins is a fluke, they have no more chance than anyone else of having twins.

It's all on probablitiy. Twins are made by either 1 sperm, 1 egg, and 2 splits, or 2 sperm, and 1 egg. So, its all a chance.
Just amke sure to check with your local laws in compliance to the 'insest' factor first!
Have a great day!

Well I think its possible. Really if it runs in the family (both or either sides). If not both of the couples, one of them should have twins. And again if it runs in the family, its really more than likely. I THINK!

The chances are very high but there is still a possibility it could not be twins.

not necessarily
the way it works to have twins if 2 sperm cells enter the egg at the same time
