Attached-X female Drosophila oocytes of various ages were irradiated, and the frequency of detachment deter mined in females of various ages. There is an increase in radiation sensttivity of oocytes with aging up to three days, after which there is no evident increase. A two hit formation of detachments ts found both in young and oid oocytes. Dose fractionation experiments show breaks in stage 7 rejoin in about ten minutes, whiie those in stage 14 do not rejoin untii fertilizatton. There is evidently a change in the proportions of the various kinds of exchanges obtained when females are aged before treatment. Speculations are made as to the possibie roie of cytochrome oxidase activity in the changing sensitivity of oocytes. (auth)
