Vedclass · Answer

(a) : The term mutation was coined by Hugo de Vries $(1901)$ for large spontaneous inheritable changes which occur suddenly in naturally reproducing population. He also proposed mutation theory of evolution in his book &ldquo;The Mutation Theory&rdquo; published in $1903$ in which he put forth that evolution occurred due to large discontinuous variations. He worked on Oenothera lamarckiana or evening primrose. During his experiments he found $834$ mutations in a population of $54343$ plants. It was later on found that the mutations observed by Hugo de Vries were actually chromosomal aberrations.
