The effect of MIP radiation on survival of fruit flies with tefu−/−, the fruit fly gene similar to the human ATM gene. At surface level, offspring from heterozygous tefu+/− flies consists for about 2% of flies homozygous for tefu−/−. This effect happens independently of background strain, as shown for wildtype A and B. The mutation does not alter the number of eggs produced or the number of eggs hatched (77% each at surface and underground level), but only deep underground in the absence of nearly all MIP radiation do tefu−/− eggs develop into the expected number of fruit flies. Arrows mark sequential experimental results. Adapted from Morciano et al. (2018).
