Question

Who rediscovered Mendel’s work?

Answer 1

Hint:- In the year 1900, a decade after Mendel wrote his papers, three botanists independently re-discovered the work of Mendel. They helped broaden understanding in the science world of the Mendelian laws of inheritance.

Complete step-by-step solution:- Mendel performed analyses of 34 different strains of peas after exploring different animal and plant environments, and selected 22 kinds for further experimentation. He preferred to study characteristics that were distinct and discontinuous and demonstrated strong superiority and recessiveness trends.

Often known as the first law of Mendel, the "law of segregation" applies to Mendel 's evidence that recessive characteristics reappear in predictable patterns. The now-famous 3:1 ratios were generated by crosses of peas which varied in one characteristic. Complex studies which followed the variations of two or three characteristics led to the recombination patterns now known as the second law of Mendel, or the "law of independent assortment."

At a meeting of the Brno Society for Natural History in March 1865, Mendel presented his findings and published in the 1866 issue of the Society's Proceedings his paper "Work on Plant Hybrids." He also submitted reprints to influential scientists of his paper, but got no publicity and almost no comprehension.

Contemporaries tended to disregard the "numbers and percentages" of Mendel as purely numerical and devoid of a respectable system of philosophy. However, Sir Ronald A. Fisher argued that the experimental design recorded in the classic paper of Mendel was so exquisite that the experiments had to be a proof, or demonstration, of a hypothesis previously proposed by Mendel.

In addition, Fisher concluded that Mendel's ratios are closer to the statistical expectation than the theory of sampling would suggest, and he maintained that without a "pure miracle of chance" certain findings could not be achieved. While Mendel was discouraged by the scientific community's lack of reaction, he remained persuaded of the fundamental importance and universality of his work.

However, Mendel and his laws were 'rediscovered' by Hugo Marie de Vries, Karl Franz Joseph Correns, and Erich Tschermak von Seysenegg at the beginning of the twentieth century, securely adding the name of Mendel to the fundamental laws of genetics. William Bateson, who, through his own research, came close to rediscover Mendel 's laws, became one of the earliest proponents of Mendelian genetics.

So from these discussions we can conclude that Hugo Marie de Vries, Karl Franz Joseph Correns, and Erich Tschermak von Seysenegg were the one who rediscovered Mendel’s work.

Note:- While the name of Gregor Mendel is now linked to the basic laws of genetics, for over thirty years his study was largely neglected and mistaken. A modern system able to fit Mendel's "ratios and numbers" was developed between the 1860s and 1900 in the study of cell division, fertilisation, and the behaviour of subcellular structures.
Science historians say that, before discovering Mendel 's article, de Vries, Correns, and Tschermak sought to highlight their own ingenuity by pretending to have found the rules of inheritance. Citing the previous work of Mendel also helped them escape a target war.
