Zoological effects of variations in atmospheric oxygen levels

The role of certain gene enzymes in survival in modified atmospheres was examined. Chromosome morphology was studied. Mortality and life span were measured. Equipment to deliver various gas mixtures to the flies was designed and fabricated. To study the gene enzymes a technique called starch gel electrophoresis was needed. Equipment and supplies for this work and the study of chromosome morphology was available on the market, although some of the equipment was fabricated to save the project money.
