Specifically regarding the founder of Genetics, one must check the resourceful MendelWeb. An English translation of his 1965 paper, as well as an exhaustive discussion of the genuinity of his work, are available online.
Then, a history of Genetics from 1900 to 1953, the Barbara McClintock papers,


Lehle Seeds makes for the best entry point for Arabidopsis thaliana in the Web, for its excellent resource page hosting for the visitor a enviable collection of links (if not structured) to "everything Arabidopsis".

Just in case, in my site you can find a page directing to my scholar texts (in Portuguese), one of them dealing with the practical use of Arabidopsis thaliana for teaching.


Online Mendelian Inheritance in Man, a vital reference both for fundamental and for clinical research in Human Genetics, that once existed as heavy books, but now at the click of the mouse. All known phenotypes, pathological as well as normal, are collected and organised for the use of the scientific community. An obligatory link with genomes research, human and others.

Literature sources

All things Biological (links and usenet discussion groups) for one to have in the favourite bookmarks set:
The BioSciences Site. At Harvard University one can look at the Golgi BioPages and most certainly some useful links will come up. Another general-purpose site, with thoughtful and well-written articles on all fields of Biology, is the Life and Earth Sciences sections at about.com.

Biomedicine-oriented users have all reasons to become members of the BioMedNet.

PubMed has the largest biomedical literature database online. It forms the basis for searching for so-called Alternative Medicine.

The old UnCover Reveal resource has teamed with Ingenta to make an excellent reference resource.

The Biochemical Genetics site from the University of California at San Diego is an excelent reference in the field.
