Table 1. Sex and genotype ratios of Sdhd KO mice.

not all mice could not genotyped.
Sex and genotype ratios of the offspring of +/− mice backcrossed with wildtype mice of the 129P2/Ola and C57BL/6J genetic backgrounds are normal. Absence of live homozygous offspring from the crossing of heterozygous mice (129P2/Ola +/−×+/−) indicates that homozygous loss of Sdhd is not compatible with life.
