July 25 Exploring Brno (Day 302)
A day of religious and cultural exploration! We set out early enough to ensure the cathedral was open for viewing and climbing the bell tower.
We continued on to the main square of old town where there was a farmers market in progress.
Down one street from the square we reached ‘Bishops Courtyard’, where scientific history was made in the 1860’s! The science of genetics began when Gregor Mendel, an Augustinian monk in Brno, conducted experiments with pea plants over several generations from 1856-1863 and deduced that characteristics are inherited from parent plants as distinct units, one from each parent, and that these characteristics can be ‘dominant’ or ‘recessive’, sometimes skipping generations. His work was not recognized for its importance until after his death. In 1900 several other researchers expanded on his 3 “Laws of Inheritance” and further research eventually led to the discovery of DNA as the “units” inherited from the parents. Fast forward to 1975 and I’m in high school learning about Gregor Mendel and genetics and the subsequent research that identified the mechanism of inheritance as DNA. In 1978 I’m in a lab in college painstakingly counting anesthetized fruit flies, separating them by the color of their eyes and the curliness of their wings, breeding them and back-breeding them and again counting them, in order to determine their genetic make-up for my class final exam! The fruit fly is the first animal to have its genetic code fully mapped. Here I am standing in the courtyard where it all began! Unfortunately it was closed and under construction! But it was exciting non-the-less!
We moved on to other highlights in Brno!
After a long day walking around town, up and down tower staircases, we headed back to our B&B.
