Exactly 156 years ago, on 8 March 1865, Gregor Johann Mendel presented the results of his experiments on plant hybrids. His colleagues from the Society of Natural Society were hardly as impressed as they might have been, had they but known they were witnessing the announcement of one of the greatest discoveries in the history of mankind. To commemorate the occasion, Masaryk University Press has prepared a special Mendel Day 2021 sale on Mendel-related books, which you can find here: https://munishop.muni.cz/obchod/kolekce-knihy/mendel-day-2021.
