This reciprocal translocation was found by fertility screening of progeny of male mice exposed to 600 rad X-rays to the hind part of the body and mated immediately afterward, during the pre-sterile period. Analysis of giemsa- (G-) banded chromosomes placed the cytological breakpoints at bands 7B3 and 19D1. The genetic breakpoints were determined by duplication-deletion mapping to lie between Gpi1 and Oca2 on Chr 7 and between Papss2 and Hps6 on Chr 19. (J:5959, J:34742)
