Inbr (Brk) 93. Black a, f, rd. Origin: f, flexed-tail gene (causing microcytic anaemia) originally obtained from Jay came from Snell's WA linkage testing stock. Seven rounds of cross-intercross to C3H by Jay and E.S. Russell. Outcross to WB/Re by Re, with b x s mating of f/f progeny started in 1956. Charac. Foetuses and new-born f/f mice show a transient siderocytic anaemia which is cured by 14 days. Variable belly spotting and tail flexure. Good breeding performance when young, later impared by obesity. Maint. by Brk.
