The Effect of Heterochromat in on Genes Located Within Heterochromatic Areas of Standard Chromosomes of Drosophila Melanogaster
(Creighton University, 1975)
The objective of this research is to determine the effect of heterochromatin on genes found within heterochromatic regions of standard chromosomes of Drosophila melanogaster. | The system used in this investigation involves ...
Mechanisms of Pteridine-Ommochrome Interactions in Drosophila Melanogaster
(Creighton University, 1974)
Ommochromes (brown pigments) and certain pteridines (red pigments), contribute to the typical reddish-brown eye color of wild-type Drosophila melanogaster. Each pigment is the end product of a seemingly unrelated metabolic ...
Genetic Mechanisms of Leg and Haltere Imaginal Disc Defects in Two Tumorous-Head Strains of Drosophila Melanogaster
(Creighton University, 1977)
Strains of Drosophila melanogaster that carry the tumorous- head trait are characterized by amorphous growths which occur in the head region of the flies. This trait, symbolized tu-h, is extremely variable in expression ...
Interaction Between Pteridine and Ommochrome Biosynthesis in Drosophila Melanogaster
(Creighton University, 1973)
Morgan (1910) described the first eye-color mutation (white) in Drosophila melanogaster. Since that time, at least 60 eye-color mutants resulting from both spontaneous and induced mutations have been reported (for index, ...
