Inbred Strains of Mice: KE

KE

Inbr:F94 (Kw). Genet: a, b, c, P. Origin: Krzanowska 1952, from mice of unknown origin; cross also produced KP.


Characteristics

Mean litter size 6.1; low percentage of fertilised ova. 17.6% of spermatozoa have abnormal heads, the inheritance of this character being connected to the Y chromosome and may be due to a rel. deficiency of androgens (Bartke and Krzanowska, 1972). Sperm head shape, the level of sperm abnormalities and fertilizing capacity are determined largely autonomously by genes acting in the germ cells. (Krzanowska et al 1991).
