Table 5. Sister chromatid exchange is increased in solo mutants.
Genotype | Ring progenya | Rod progenya | Ring/Rod |
R(1)2, y f/y w; +/+ | 958 | 1156 | 0.83 |
R(1)2, y f/y w; Df(2L)A267/soloZ2-0198 | 209 | 605 | 0.35 |
R(1)2, y f/y w; Df(2L)A267/soloZ2-3534 | 216 | 604 | 0.36 |
The indicated females were crossed to w1118/Y males.
Ring-X and Rod-X progeny were recognized by w+ (red) versus w (white) eyes, respectively.
See Materials and Methods for cross details. Only regular (disjunctional) progeny are included in the table and in the calculated ratios.
