Question

Carl Correns a rediscoverer of Mendel's work was from
a. Austria
b. Germany
c. Holland
d. Denmark

Answer 1

Hint: Carl Correns was a botanist and geneticist, he had various independent discoveries, among all, he became very notable for the discovery of the principles of the hereditary, when he achieved so many things, and later he collaborated with the botanist Hugo de Vries for the rediscovery of Mendel’s work.

Complete answer:
- Carl Correns was a German botanist, where he is the student of Karl Nageli, who is the renowned botanist, where is working together with peas experiments with him, and where subsequently engaged in a long exchange of the letters regarding the results of some species called Hieracium.
- Most of the experiments with this species have failed mainly because of its special properties, and where the Mendel dropped the experiment.
- Col Correns, he independently rediscovered and verified the work of Mendel in a separate model.
- He also discovered cytoplasmic inheritance and an important part of the Mendel's theory.
- Correns found that Mendelian traits behave independently and irrespective sex of the parent plant.
- He has done experiments on Mirabilis Jalapa, where the pollinating the ovule from the white branch with the pollen from the other white area, results in the white progeny, where he predicts the results for a recessive gene
- If the Green pollen is pollinated with the green flower ovule, it results in the green progeny and the results predict for the dominant gene.

Hence, the correct answer is option (B).

Note: Later Non-Mendelian pattern of the genes was discovered by him, and he states that only the functional genes are inherited to the progeny, where later he established a paper, and published the leaf color as an example for cytoplasmic inheritance.
