This is sci.bio, not sci.philosophy.meta.  Please keep semanticism in the
right newsgroup.  Most USENET readers don't need every word explicity de-
fined.

The way I learned it ("Biology" by Helena Curtis), after meiosis II, the egg
is the only cell to survive and ever pass into the fallopian (sp?) tube.  To
my knowledge, the polar bodies die and are later ingested by white blood
cells.  Plus, I tend to agree that even if a polar body was fertilized, there
would not be enough cytoplasmic material for the zygote to survive long enough
for implantation on the uterin lining.

I don't know how you rank beginners, but I did take my college level biology
course, and thus, must draw on that as my body of knowledge.  And it is YOUR
semantics in taking my phrase "very impossible" too literally, not my presump-
tion of biological knowledge.  Anyways, I don't think the basic ideas in bi-
ology are going to change according to how much you know, just as 2 + 2 will
still equal 4 even if I know how to do double integrals!
