Toshihiko SHIROISHI T, Brachyury, semidominant, Chr 17. t, t-complex, recessive, Chr 17. 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.
