Genetics and biochemistry of "red cells" in Drosophila melanogaster
Studies were made of the "red cells" strain of Drosophila melanogaster. "Red cells" flies are characterized by the presence of reddish pigment in certain fat cells. A genetic analysis revealed that the fat cells are pigmented only when flies are homozygous for two mutant genes....
