Effects of the Mom1 and Mom2 Loci on the Incidence of Colon Polyps in N2 Offspring from the B6 × D2B6F1 ApcMin and D2 × D2B6F1 ApcMin Backcrossesa
Genotypes of B6 × D2B6F1 ApcMin N2 offspring | Mom1S/Mom1S | Mom1R/Mom1S | p values |
---|---|---|---|
Mom2+/Mom2+ | 71.4% (5/7) | 37.5% (3/8) | p = 0.3147 |
Mom2R/Mom2+ | 8.6% (3/35) | 3.4% (1/29) | p = 0.6198 |
p values | p = 0.0012 | p = 0.0256 |
Genotypes of D2 × D2B6F1 ApcMin N2 offspring | Mom1R/Mom1S | Mom1R/Mom1R | Total |
---|---|---|---|
Mom2+/Mom2+ | 66.7% (2/3) | 50.0% (1/2) | 60.0% (3/5) |

aN2 progeny of D2B6F1 ApcMin parents #5, #6, and #7 from Table 1 were classified according to strain background as well as genotype and phenotype at the Mom1 and Mom2 loci, respectively. The % of mice within each class is given. The numbers in parentheses show the actual number of mice with ≥1 colon polyp over the total number of mice in each class. P values were determined by the Fisher's exact test.
