Simple Mendelian genetics are not usually very simple in the real world. In a lab or in special circumstances they can be relatively simple but in a cultivated/domesticated plant whose breeding population may have been formed from crosses between different species and sometimes between many different species they can be very complex....

I really appreciate your efforts, will continue with Bozeman site, the first to mention the implications of the my note "Independent assortment genes(traits) operate independently" and the very relevance of it.

Will also do some searching on the pigments in relation to Echinopsis.

Thanks again.
