Reference

Remark
Translocation of short arm of chromosome 4 of Agropyron intermedium into chromosome arm 4DS of Triticum aestivum.
When a translocated alien fragment is in a wild-type Ph1 background it no longer recombines with wheat chromatin (or only at very low frequencies). Therefore, the segment is inherited as a whole, so if there is a molecular marker located within the fragment containing the translocated gene, the genetic distance to the gene would be zero, even when the physical distance could be very large.
