The genetic basis for the DBA/2-C57BL/6 difference in susceptibility to cortisone-induced cleft palate is relatively simple. One dominant gene on chromosome 5 contributes predominantly to the strain difference in susceptibility, but the embryonic response appears also to be influenced by genes on the X chromosome. The H-2 haplotype does not affect the cortisone-induced cleft palate response in the two congenic strains C57BL/10 (B10) and B10.A by altering the stage of palate closure.
