Table 1.
Background | E2f3a-/- observed | χ2 test p value |
---|---|---|
E2f3a Mix (C57BL/6 × 129Sv) | 24% (23/94) | 0.534 |
E2f3a Pure (129Sv) | 23% (60/257) | 0.615 |
E2f3a+/- mice on the indicated backgrounds were crossed and the pups genotyped at three weeks of age. The indicated frequency of mutant animals was not significantly different from the expected frequency as judged by a χ2 test.
