BTBRTF and BTNTTF

Inbr. F100+?. Black-and-tan, brachyury tufted. Genet: a^t, B, tf, T/+ or +/+, H2^b . Origin: Dobrovolskaia-Zavadskaia to Dunn who sib-mated at the Nevis Biological Station, Columbia University. Tufted from Dr. Mary Lyon was backcrossed onto the strain, followed by further sib mating. To Dorothea Bennett from 1962, then to Karen Artzt. Supports maintenance as a balanced lethal stock with matings of T/t x T/t. Has been selected for 50% tail length of T/+ heterozygotes. The normal tailed segregant is sometimes known as BTNTTF. Good breeding performance (Artz personal communication, July 1997 and Artz et al, 1977).
