Fig. 6.
Genotypes for chromosome 4 (gray bars) and chromosome 13 (striped bars) of individual B10.TCRδ−/− × B6.TCRδ−/− F2 females. Results for the 6 F2 females only are shown in the left panel; no association between the development of keratitis and inheritance of a particular genotype is evident for either chromosome. Genotypes of all 61 F2 females obtained are shown in the right panel; for each genotype - B10/B10, B10/B6, and B6/B6 - frequencies close to the predicted Mendelian ratios of 1:2:1 were observed.
