Question

The idea of mutations was brought forth by

• A. Hugo de Vries, who worked on evening primrose
• B. Gregor Mendel, who worked on Pisum sativum
• C. Hardy Weinberg, who worked on allele frequencies in a population
• D. Charles Darwin, who observed a wide variety of organisms during sea voyage

Answer 1

The correct option is A Hugo de Vries, who worked on evening primrose

Hugo de Vries did his genetic experiments with Oenothera lamarkiana (evening primrose) and gave the "Mutation theory". Gregor Mendel worked on Pisum sativum and proposed the laws of inheritance; he did not explained the variations found in his results. Hardy Weinberg studies the allele frequencies in a population that are not evolving. According to Charles Darwin, minor heritable variations are basis of evolution, not the mutations. He proposed the theory of natural selection to explain the process of evolution.
