What was the title of the paper written by Gregor Johann Mendel and published in 1866?

Correct option is A

The correct answer is (A) Experiments on Plant Hybridization

Explanation:
• Gregor Mendel, known as the 'Father of Genetics', presented his findings to the Natural History Society of Brünn in 1865.
• The paper was published in the society's journal in 1866 under the German title "Versuche über Pflanzen-Hybriden".
• In English, this is translated as "Experiments on Plant Hybridization".
• In this work, Mendel outlined the laws of inheritance (Segregation and Independent Assortment) based on his eight years of study on pea plants ($Pisum$ $sativum$).

Information Booster:
• Mendel's work remained largely ignored for 34 years until it was rediscovered in 1900 by three scientists: Hugo de Vries, Carl Correns, and Erich von Tschermak.
• Mendel chose pea plants because they had clear contrasting characters and were easy to cross-pollinate.

Additional Knowledge:
• Mendel studied 7 pairs of contrasting traits.
• He was the first to use mathematical logic and statistical analysis in biology.
• Options B, C, and D are descriptive phrases often used to talk about his work, but they are not the formal title of the publication.
