Subject: Is there a set reason for electron interference?

Two questions  1.)All the physics information on electron behavior 
states that there is such a thing a electron interference.  They say this 
would be demonstrated by the 2 slit experiment when electrons form a wave 
pattern similar to the pattern water would make when flowing through the 2 
slits. Is there a set reason 
this happens?
      2.) Do electrons emit any type of radiation or other waves that 
other electrons would interfere with, and if so, could it be that the wave 
interference pattern electrons form through the 2 slits is beacuse the 
electron interferes with it's own radiation or waves?
I checked all the information you had, but none really answered my 
question. If you think it has already been answered, I'll gladly withdrawl 
my question.
