TS1

Inbr. F51 (Har, 1988).

Colour: Agouti, with white on ventral surface,

Genet. A, hⁱ.

Origin: Harrington, from stock selected by Tryon in 1929 for good maze learning performance (Harrington 1981). Although TMB and TS1 are derived from the same outbred stock, they were inbred independently and should be regarded as different inbred strains (Festing 1979b).

Characteristics

Low open field activity (12/12) (Harrington 1972), low wheel activity in males (10/12) (Harrington 1971b). See also Harrington (1979a-i).
