Table 4.
TBB-1 and TBB-2 are redundant for embryonic development but are not equally preferred for katanin activity
| Maternal genotype | % hatching at 25° |
|---|---|
| tbb-2(RNAi) | 86a |
| tbb-2(gk129)b | 75 |
| tbb-1(RNAi) | 92a |
| tbb-1(gk207)c | 88 |
| tbb-2(RNAi); tbb-1(RNAi) | 0a |
| tbb-2(gk129); tbb-1(RNAi) | 0.5 |
| tbb-2(sb26); tbb-1(RNAi) | 85 |
| mei-2(ct98)d | 74 |
| mei-2(ct98); tbb-2(RNAi) | 1.7 |
| mei-2(ct98); tbb-2(gk129) | 5.8 |

a
Percentage of hatching at 20°.
b
gk129 is a predicted molecular null allele of tbb-2.
c
gk207 is a predicted molecular null allele of tbb-1.
d
mei-2(ct98) decreases but does not eliminate mei-2 activity.
