The locus for tardy feathering (t), previously mapped to the long (q) arm of chromosome 1 of the chicken, was tested for genetic linkage with both the NM 7659 t(Z;1) rearrangement break point (RB) and the henny feathering (Hf) locus. The RB is proximal to the centromere on 1q, and Hf has been reported to be on the proximal one-third of the same arm. Independent segregation of all three markers was found in two separate backcrosses.
