This strain was created by crossing “SD-Tg(Rho*S334X)3Lav, RGD: 1358302,”( also known as, SD-Tg(S334ter)3Lav , homozygous for a mutated mouse rhodopsin transgene Rho S334ter-3) with “NTac:NIH-Foxn1rnu, RGD: 7246928,” (also known as NTac:NIH-Whn (NIH nude) males (foxn1-/-). By selective breeding, all animals of this strain (RRRC#539) are homozygous for the rhodopsin mutation, and homo- or hemizygous for the foxn1 mutation.
