C3H/HeSn-Ttf/+tf strain was introduced to National Institute of Genetics from the Jackson laboratory in 1985. Sister-brother mating Heterozygote x Wild (tail defects x normal tail) false C（3〜6か月） 国立遺伝学研究所 T, Brachyury, semidominant, Chr 17. Discovered in a laboratory stock. T/T homozygous embryos die at 10 days of gestation due to failure to form a normal mesoderm. T/+ heterozygote have a shortened tail and abnormal sacral vertebrae. T/t mice are tailless. tf/tf homozygous mice show repeated waves of hair loss and regrowth. tf gene is linked to the T/t complex.
