 Origin One male rat "SRR-Rocket Science" was introduced from American fancy rat colony (Spoiled Ratten Rattery: SRR, in Kansas City, Missouri) to Kyoto University on July 13, 2005. Inbreeding started from F1 progeny of male "SRR-Rocket Science" and a female PVG/Seac. Homozygous rats for grey mutation were selected for inbreeding. (Sep 25, 2009) 
 Strain Characteristics This strain carries two mutations grey (<i>g</i>) which causes light grey body color and Pearl (<i>Pel</i>) which causes hair lighter coat color and is lethal in the embryonic period if homozygous. Genetic analyses mapped <i>g</i> to Chr 8 (Kuramoto, 2010). (May 26, 2010) 
 Breeding Conditions Maintained by crossing of heterozygous and wild-type for Pearl mutation. This strain is heterozygous for Pearl (segregating strain) and homozygous for grey. Good breeding performance. (Sep 25, 2009)
