Figure 9. Agarose gel visualization of genotyped genomic deoxyribonucleic acid samples of mice screened for the Gpr179nob5 allele and examined with electroretinogram. The yellow box highlights the observation that the no-b-wave (nob) electroretinogram (ERG) phenotype was observed only in mice that were homozygous for the Gpr179nob5 allele.
