of Mice: JU
Inbr: F41+60 (Ct). Albino. Genet: a, c.
Origin: Falconer 1952,
from crosses involving Goodale's and MacArthur's large strains, Bateman's
high-lactation strain and various mutant stocks with about 50% of C57BL/Fa
ancestry. It was the only survivor from an inbreeding experiment involving
twenty lines (Falconer, 1960b). Falconer to Cattanach in 1966.
Average first litters 9; high prenatal mortality (50%) in second litters
when gestation is concurrent with suckling first litter; low penetrance
). Lm maintains
a number of substrains with different pigment mutations including a non-albino
. Maint. by Ct.
Inbr. N5F59 (Ct). Black, a
. Derived from a cross between
JU female (F41) with a CBA male, five backcrosses to JU, then selection
for the CC
genotype upon sib mating.
Inbr. N5F59. Agouti, +. Origin: same as JU/Ct-C
, but selection
for the agouti phenotype upon sib mating. Charac. Background enhances
expression of Sl
regard to coat colour.
