Who gave the concept of mutation while working on Drosophila?
He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while apparently unaware of Gregor Mendel’s work, for introducing the term “mutation”, and for developing a mutation theory of evolution….Hugo de Vries.

Who find out the physical mutagen in Drosophila?
Using the test for sex-linked recessive lethals, Charlotte Auerbach detected the first chemical mutagens (Auerbach and Robson, 1947).
Is Drosophila a vertebrate?
Most animal testing involves invertebrates, especially Drosophila melanogaster, a fruit fly, and Caenorhabditis elegans, a nematode. These animals offer scientists many advantages over vertebrates, including their short life cycle, simple anatomy and the ease with which large numbers of individuals may be studied.
What was the name of the first Drosophila mutation identified by a person?
white, abbreviated w, was the first sex-linked mutation discovered, found in the fruit fly Drosophila melanogaster. In 1910 Thomas Hunt Morgan and Lilian Vaughan Morgan collected a single male white-eyed mutant from a population of Drosophila melanogaster fruit flies, which usually have dark brick red compound eyes.
What was Hugo de Vries mutation theory meant to explain?
On the basis of above observations, Hugo de Vries (1901) put forward a theory of evolution, called mutation theory. The theory states that evolution is a jerky process where new varieties and species are formed by mutations (discontinuous variations) that function as raw material of evolution.
What is the characteristics of Drosophila melanogaster that inspired genetics to use it as study model?
Genetic factors also make this fly an ideal model organism. D. melanogaster only has four pairs of chromosomes compared to 23 pairs in humans. This simplicity was one of the reasons why they were first used in genetic studies; Drosophila genes could be mapped easily to investigate genetic transmission.
