Fraternal twins are two different eggs and two different sperms. AFAIK. One egg and two sperm couldn't make anything viable. One egg that split into two and then got fertilized by two different sperm might, but cellular replication is pretty well stopped in an egg cell until it is fertilized so I think it more likely that it would split after fertilization (resulting in identical twins).
