        In relation between segmentation of the organisms 
and homeotic genes:
        It seems that the general view is that the 
"appearance" and evolution of homeotic genes involved 
consistently the "appearance" and evolution of 
        However, there also exist homeotic genes in 
non segmented animals.

        Could we expect, perhaps, that homeotic genes 
could "see" each segment as a whole, a non segmented 
organism, similarly to these genes in a non segmented 

        Also, could anyone tell me something about the
origin of the correlation between the arrangement of
hometic genes in each cluster and the expression domain 
in the embryonic body?

Thank you very much :-)
