I haven't been able to find a clear and simple definition of "phenotext" and "genotext", both terms — I believe — were created by Julia Kristeva. All explanations are only pompous texts I have not had time to go through. Has anyone a definition for me?
Taken from http://www.signosemio.com/kristeva/a_semanalyse.asp. (Note also her note "The distinction between the terms "pheno-text" and "geno-text" was borrowed from Šaumjan Soboleva.")
I don't know semiotics, but based on my biology background and extrapolating from the difference between phenotype and genotype, plus given the definitions above, I'd hazard:
If that doesn't help, you might want to provide some quotations from some pompous papers.
In a much simpler way, I as a commoner, would understand the terms something like this:
Pheno-text is the what of it. Geno-text is the why of it.
Your phenotype says you have blue eyes (what do you have?). Your genotype determines if you will have the genes associated with blue eyes (why so?).
Likewise, language (as an example of text) as we experience it in its appearance/ as it sounds, is pheno-text (what is the word like?). The factors influencing the nature of the same is geno-text (why is it so?)
[Since how could be confused with how it looks which is 'what it looks like', I am avoiding that descriptor.]
The original work in this area is attributed to Julia Kristeva I believe, thanks to @Kith.
