to assist in the interpretation of this somewhat unexpected observation , three additional studies were performed : ( 1 ) comparison of 'optimal ' schemes for photoreactivation of uv-induced lethal damage in the hybrid and parental g1 phase cells , ( 2 ) comparison of the effects of some different types of growth medium on photoreactivation of uv-induced lethal damage in hybrid and parental g1 phase cells , and ( 3 ) comparison of the levels of photoreactivation of uv-induced chromatid deletions in the v79m1 and a86 chromosomes of g1 phase hybrid cells .
