no, it can NEVER divide B 4 fertilization unless its asexual reproduction which i believe only takes place in few plants not human beings. always remember that there can never be any division BEFORE fertilization in humans till after the eggs have been fertilized.

No, I don't think so. I think it has to be fertilized before it can divide.
But sometimes twins are born from a *divided egg* and sometimes twins are born from two seperate eggs. That's the difference between ferternal, and identical twins.
If the woman's body produces two seperate eggs and they both get fertilized, then they are ferternal twins.
It the woman's body produces only one egg, it gets fertilized, and it splits in half, then a woman will have Identical twins.

No! In animals, after meiosis I and II is completed, haploid cells will not undergo division until is fertilized.
As Jayd said, plants do something like this. All plants have a stage called a gametophyte, made up of multicellular haploid cells that produce gametes (eggs or pollen). Its called alternation of generation. Only in plants!

Since the reproductive cells of humans only have half the requisite genome for vialble cell division (mitosis), the answer is no.

Only if you have identical twins! that is why they look the same. Same egg.
