Before Muller's discovery that radiation induces mutation, scientists had to work on spontaneous mutants that were found solely by phenotype differences in natural populations. Which of the features of Drosophila made it a fortuitous choice for Morgan and his colleagues?
A) both sexual and asexual reproduction
B) well- known biochemical pathways
C) especially high rate of mutation
D) having a long life cycle
E) large number of visible phenotypes
