of time. Inbreeding started in 1945. charac: selected for good 

 growth and reproductive performance. No known spontaneous 

 tumors, maintained by: Wi. 



inbr (Wi) : 44. genet: aacc. H-2 q . origin: same as BUA. charac: 

 same as BUA. maintained by: Bn, Wi. 



inbr (Wi) : 36. genet: aacc. origin: same as BUA. maintained 

 by: Wi. 



inbr (Wi) : 19. genet: albino, origin: cross betweeen BUD at 

 F 18 (now discarded) and BUA at F 14 . charac: selected for circling 

 now 20% penetrance. Onset 14-20 days. Audition and vestibula- 

 tion present and apparently normal. Circlers vicious fighters; not 

 good mothers. Very high metabolic activity, maintained by: Cu, 

 Wi. 



inbr (St): 86. genet: bb. H-2". origin: Strong (see C3H/St). 

 charac: moderate mammary tumor incidence. Tendency to bi- 

 furcation of seminal vesicles, maintained by: Ao, St. 



inbr (Jax) : 106. genet: 4-. H-2 k . origin: (see C3H/St). charac: 

 mammary tumor incidence variously reported l.l-22.2%. 742 Some 

 hepatomas. Long-lived. Dietary supplements needed to maintain 

 reproductive efficiency. Absence of lower third molars in about 18%. 

 Few skeletal variants. Moderately resistant to skin cancer induction 

 by chemical carcinogens, maintained by: Br, Cbi, Fa, Gr, H, Jax, 

 Lab, Lhm, Ms, No, Rij, Ss, St. 



inbr (Pa): 28. genet: 4-. origin: Paterson, from CBA mice 

 received in 1949 from Carr and fostered on C3H. charac: spon- 

 taneous mammary cancer, maintained by: Pa. 



inbr (Be): 20 4-. genet: aa. origin: Carter outcrossed CBA to aa 

 and backcrossed to CBA to N6. B x s matings thereafter, main- 

 tained by: Be. 



inbr (H): N5 + F24. genet: +a l x a 1 a 1 , origin: CBA/Fa. 



MAINTAINED BY: Fa, H. 



inbr (Fa): ? 4- 31. genet: +da, dada. origin: Dark (da) arose in 

 CBA/Fa circa 1955. charac: like CBA. maintained by: Fa. 



inbr: ? + 16. genet: +. origin: from Bonser to Miihlbock, to 

 Rijswijk in 1953. charac: not H-2 k , but an as yet unknown H-2 

 type, maintained by: Rij. 



inbr (Cam): ? 4- 16. genet: +p x pp. origin: mutation in 1948 

 or 1949 in CBA/Ca. maintained by: Cam. 



inbr (Gn): 30. genet: +se x sese. origin: mutation in 1948 or 

 1949 in CBA/Ca stock, charac: high incidence of hydronephrosis in 

 sese animals, maintained by: Cam, Gn. 



inbr (Mv): 41. genet: brown, origin: see CC57W. The same 

 cross produced both CC57BR and CC57W. charac: do not develop 

 spontaneous mammary tumors; 55% tumors after administration 

 of milk agent to newborns. 1 % pulmonary adenomas in old mice, 

 15% after urethan treatment. Probably differs from CC57W in 

 leukemia incidence and H-2 allele, maintained by: Mv. 

 inbr (Mv) : 40. genet: albino, origin: C57BL and BALB/c mice 

 received in Moscow, Sept., 1943, from Nat. Inst. Health (USA).
