Question

Carl correns, a rediscovery of Mendel's work, was from?
A. Austria
B. Germany
C. Holland
D. Denmark

Answer 1

Hint: Carl Erich Correns was a German botanist and geneticist. He is known primarily for his independent discovery of the principles of heredity, and for his rediscovery of Gregor Mendel's work. He achieved this simultaneously but independently of the botanists Erich Tschermak von Seysenegg and Hugo de Vries, and the agronomist William Jasper Spillman.

Complete answer: Carl Erich Correns was born on 19 September 1864 and died on 14 February 1933. He was a German botanist and geneticist. He was known primarily for his independent discovery of the principles of heredity, and for his rediscovery of Gregor Mendel's work on genes.

Gregor Mendel worked on pea plants and discovered the fundamental laws of inheritance. He determined that genes come in pairs. They are inherited as distinct units, one from each parent. Mendel tracked that segregation of parental genes and their appearance in the offspring is determined as dominant or recessive traits.

Rediscovery of Mendel's work
In 1892, Correns began to experiment with trait inheritance in plants at the University of Tübingen. Correns published his first paper on 25 January 1900, illustrating both Charles Darwin and Mendel, recognizing the relevance of genetics to Darwin's ideas. In Correns' paper known as, "G. Mendel's Law Concerning the Behavior of the Progeny of Racial Hybrids", he restated Mendel's results as the' law of segregation' and introduced a new 'law of independent assortment'.

So, the correct option is B,- ‘German’.

Note: Gregor Mendel published his work in 1866. In his work, he demonstrated the actions of invisible "factors", which are now called genes. He did this predictably determining the traits of an organism. The profound importance of Mendel's work was not recognized until the turn of the 20th century which was more than three decades later. This happened with the rediscovery of his laws by Carl correns.
