Table 1. Distribution of genotypes from crossing Hras+/-;Nras+/- mice.
| Genotype | Expected ratio % (#) | Observed ratio % (#) |
|---|---|---|
| Hras+/+;Nras+/+ | 6.25 (16.75) | 7.46 (20) |
| Hras+/-;Nras+/+ | 12.5 (33.5) | 13.06 (35) |
| Hras+/+;Nras+/- | 12.5 (33.5) | 12.31 (33) |
| Hras+/-;Nras+/- | 25.0 (67) | 24.25 (65) |
| Hras-/-;Nras+/+ | 6.25 (16.75) | 5.22 (14) |
| Hras+/+;Nras-/- | 6.25 (16.75) | 7.46 (20) |
| Hras-/-;Nras+/- | 12.5 (33.5) | 12.69 (34) |
| Hras+/-;Nras-/- | 12.5 (33.5) | 14.18 (38) |
| Hras-/-;Nras-/- | 6.25 (16.75) | 3.36 (9) |
18 pairs of Hras+/-;Nras+/- mice were bred to generate 268 pups. The percent and number of pups with each of the 9 possible genotypes (observed ratio) is show in comparison to the expected frequency based on Mendelian ratios (expected ratio).
