Vedclass · Answer

(A) : The term mutation was coined by Hugo de Vries $(1901)$ for large spontaneous inheritable changes which occur suddenly in naturally reproducing populations.He also proposed the mutation theory of evolution in his book "The Mutation Theory" published in $1903$, in which he stated that evolution occurred due to large, discontinuous variations.He worked on $Oenothera$ $lamarckiana$, commonly known as the evening primrose.During his experiments, he observed $834$ mutations in a population of $54343$ plants.It was later discovered that the mutations observed by Hugo de Vries were actually chromosomal aberrations.
