Table 2.
Background | E2f3b-/- observed | χ2 test p value |
---|---|---|
E2f3b Mix (C57BL/6 × 129Sv) | 27% (47/176) | 0.248 |
E2f3b Pure (129Sv) | 33% (28/85) | 0.256 |
E2f3b+/- mice on the indicated backgrounds were crossed and the pups genotyped at three weeks of age. The observed frequency of mutant animals was not significantly different from the expected frequency as judged by a χ2 test.
