[00:00.63]4.The Father of Genetics


[00:04.55]His name is introduced to biology students, but often forgotten after the final exam.


[00:10.76]His pioneering discoveries went unnoticed by the world until years after his death.


[00:15.88]But now, in the era of genetic 1 engineering and cloning debates, 


[00:20.45]scientists are elevating Johann Gregor Mendel to his rightful place in history alongside better-known,


[00:28.40]19th century contemporaries such as Charles Darwin.


[00:32.21]Experts and scientists have collected artwork and artifacts inside the partially 2 restored Abbey of St. Thomas in Brno,


[00:41.14]a Czech city where Mendel lived, experimented with pea plants and published his historic findings in 1866, 


[00:49.52]becoming the “father of genetics”.


[00:52.57]The abbey, which dates from the 14th century, was seized from the Augustinian monks 3 by communists in 1950 


[01:00.85]and returned to the religious order after the Velvet 4 Revolution in 1989. 


[01:06.30]A restoration project began in 1996. Yet much of the stone complex remains 5 unused.


[01:14.24]Mendel was born to a farming family in what’s today the eastern Czech Republic. 


[01:20.01]He became a priest in 1847 and later studied science at the University of Vienna. 


[01:26.00]Fascinated, by plant hybridization, he began experimenting in the abbey garden with pea plants.


[01:32.54]During the 1850s Mendel carefully and systematically 6 crossbred the plants 


[01:38.96]until reaching conclusions that form the basis for the laws of heredity. 


[01:43.64]He presented his landmark 7 paper in 1865 and had it published the next year. But no one noticed.


[01:51.70]According to scholars, Mendel’s contemporaries failed to grasp the significance of his discoveries. 


[01:58.56]But around 1900 — long after his death in 1884 — a British zoologist 8 re-introduced the Czech scientist and his work, 


[02:07.93]sparking an era of medical, agricultural and scientific progress that continues today.


[02:14.03]Indeed, thanks to Mendel and his peas, modern man understands why children inherit their parents’ traits, 


[02:20.92]what roles are played by chromosomes 9 and DNA 10 in living things and how genetics can be used to improve human health. 


[02:28.80]Around 1996, his findings led to the famous cloning of Dolly the sheep, 


[02:34.82]as well as ethical 11 debates over human cloning and farming with genetically 12 modified crops.
