Question

Carl Correns, a rediscoverer of Mendel's work, was
a. American
b. German
c. Austrian
d. Spanish

Answer 1

Hint: September of the year 1864 is the day where the scientist Carl Correns was born in Munich. Since he was orphaned at an early stage, his aunt took the responsibility of raising him in Switzerland. In the year of 1885, he entered the University of Munich. The scientist Karl Nageli encouraged him to study botany. Correns became a tutor at the University of Tubingen, after finishing his thesis.

Complete answer:
- We can say that the scientist Carl Erich Correns was notable by every person primarily due to his independent discovery of the principles of heredity.
- As we already know that he was also famous for his rediscovery of earlier papers by Gregor Mendel on a certain subject. One can say that the scientist Carl Erich Correns made many achievements.
- He was succeeded in working independently of the agronomist William Jasper Spillman and Hugo de Vries, and botanists Erich Tschermak von Seysenegg.

Hence, the correct answer is option (B).

Additional information:
- In the year of 1913, he became the first director of the Kaiser Wilhelm Institute for Biology which was newly founded in Berlin-Dahlem in the year of 1913. He married Elisabeth Widmer, who was a niece of Karl Nageli.
- The plants like Hieracium have special properties. Because of these precise traits of the plant, the experiments made by the scientist Mendel were failed. In turn, this led him to drop his studies on the subject. However, Carl Correns made an effort and discovered many things about such plants.

Note: The scientist Carl Erich Correns was a student of Karl Nageli. He became a renowned botanist later for his priceless work. He was a talented scientist with whom Mendel corresponded about his work with peas. He was also the one who subsequently involved in a long discussion of letters relating to the reproducibility of the consequences in another species (such as Hieracium).
