Milislav Demerec discovered highly mutable alleles of two genes in D. virilis, miniature and magenta (Demerec 1926; 1927; reviewed in Demerec 1935; Green 1976). Both genes were mutable in soma and germ-line and. for the miniature-3alp The transposable elements of the Drosophila melanogaster euchromatin – a genomics perspective.ha alleles, dominant enhancers of mutability were also isolated by Demerec.
