Adaptive response to dominant lethality of mature (class A) and immature (class B) oocytes of D. melanogaster to low doses of ionizing radiation: effects in repair-proficient (yw) and repair-deficient strains (mei 41D5 and mus 302D1).

Abstract excerpt

Mature oocytes (class A) and immature oocytes (class B) from a repair-proficient yw strain and two repair-deficient strains (mus 302D1 and mei 41D5) were initially X-irradiated with 0.02 Gy and subsequently treated at various time intervals with 2 Gy. They were tested for dominant lethality (early and late death). For each strain and stage the observed values were below those expected on the basis of additivity...
