TS3

Inbr. F55.

Colour: Black,

Genet. a.

Origin: Harrington, from stock selected by Tryon for poor maze learning performance (Harrington 1981). Although TMD and TS3 are derived from the same outbred stock, they were inbred independently and should be regarded as different inbred strains (Festing 1979b).

Characteristics

High open field ambulation (4/12) and low defecation (9/12 males 10/12 females) (Harrington 1972). Short latency to emerge into a novel (3/12 males, 2/12 females) and familiar (3/12 males, 4/12 females) environment (Harrington 1971a). See also Harrington (1979a-i).
