Chromosomal Organization

There may be some relationships between gene expression during embryonic 
development and the logical organization of the genome. To what extent 
this will reflect physical organization of the chromosomes is difficuly to 
determine. Consider a hierarchical Pascal computer program. What is its 
physical structure on your hard disk? If you knew the latter, what would 
it tell you about how the program works?

Please see the appended request. Thanks, -Dick Gordon[Dec4,94]

Dear Colleague:

I am finishing a book about the intersection of three major fields of 

Gordon, R. (1995). The Hierarchical Genome and Differentiation Waves:
Novel Unification of Development, Genetics, and Evolution  (Singapore:
World Scientific), in prep.

and refer to your work. I would appreciate reprints or preprints as soon
as possible, or an update, if I've been in contact with you previously.

Please be sure to include your e-mail address in case I have any questions.

Thanks for your help.

Best regards, -Dick Gordon
