Frequency of Inka1 null progeny at weaning.

Parental cross Total at weaning Genotype # observed (#expected) X2 P
Inka1+/+ Inka1+/− Inka1−/−
Inka1+/− X Black Swiss 67 32 (33.5) 34 (33.5) N/A 0.061 0.806
Inka1+/− X Inka1+/− 69 24 (17.25) 34 (34.5) 11 (17.25) 3.019 0.082

Chi-square test was applied to results of mating scheme shown in lines one and two to examine ‘goodness-of-fit’ to normal Mendelian ratios.
