Nope, it doesn't have the identical genetic expressions as the parent. 
All multicell creatures have two chromosomes with the potential for
differing traits on each of those chromosomes.  While the offspring of
self fertilization would share a larger percentage of traits with the
parent than with normal fertilization, there is still the potential for
vast difference in appearance and function (for instance it might
inherit chromosome 1 a or b, and chromosome 2 a or b etc.  Figuring that
a plant may have 30-300 different chromosomes all with genes for various
functions, you can see that there is still plenty of room for variation
even in a closed system.  The danger in this closed system is that the
new individual stands a much greater chance of inheriting recessive
lethal or detrimental genes which might impair function and may cause
death.  D. Petersen

Clones share 100% the same genetic material.
