Inbr (Nctr) 74. Variable yellow to agouti and black: A^vy/a, a/a. Origin: The A^vy mutation occurred in C3H/HeJ in 1960. Crossed with a C57BL/6J male, then backcrossed to C57BL/6J. One N3 male and two N1 females from M.M.Dickie, Jackson Lab. to Inst. Cancer Research in 1962. These were mated and the offspring sib mated. Maintained by A^vy/a, a/a matings since then. To the Nctr in 1972 at F35. Caesarian derived and fostered on C3Hf in 1977 at F47. Pseudoagouti phenotype about 10% of A^vy/a mice. Spontaneous hepatocellular tumours in 24% of male yellow mice but only 13% of black mice. Phenotypically yellow mice differ from agouti ones in a range of biological properties (Wolff et al 1990). Maint. by Nctr.
