EXPERIMENT INFORMATION

Genetic Effects of the Space Environment on the Reproductive Cells of Drosophila Adults and Pupae (P-1159)
Principal Investigator
Research Area:
Developmental biology
Species Studied
Scientific Name: Drosophila melanogaster Species: Fruit fly

Description
Objectives:

This experiment was designed to study possible transmissible genetic damage in the fruit fly caused by exposure to the conditions of space flight combined with continuous ionizing radiation. The large variety of specimens for both stages of maturity and genotype of reproductive cells gave the project an exploratory nature; it was to be followed by careful selection, after return of data, of material most suitable for testing in space.
