A one-egg twin would be identical twins. This is the result of one egg being fertilized by one sperm, then the very early zygote will split and form two.
However, if you have fraternal twins, then you need two eggs and one sperm for each, thus 2 sperm.

1 sperm for one egg. the egg divides in two to form twins(identiclas)... however, 2 sperms can penetrate 2 eggs and each form a baby (2 babies in total that are not iddentical)

It only takes one..sometimes in twins its the egg that splits into two..or there are two eggs present...now in that case im not sure if it would take more than one sperm.

one, because the egg cell splits into two when the sperm fertilises it (i think)

One egg is fertilized, forming one zygote. The zygote then divides and forms two separate embryos.
