## Abstract Summary: To facilitate genetic screens to identify and maintain recessive mutations that map to the short arm of human chromosome 1, we have utilized chromosome engineering to generate two mouse strains that carry large inversions on the distal region of mouse chromosome 4. The inversio

โฆ Synopsis
The genes for orosomucoid (ORM-1 and ORM-2), delta-aminolevulinate dehydratase (ALAD), and hexabrachion or tenascin (HXB) all map to the q31-qter region of human Chromosome (Chr) 9. The mouse homolog of each of these genes has been mapped to Chr4, but hexabrachion has not previously been mapped by linkage analysis. We have now ordered Orm-1, Lv (the mouse homolog of ALAD), and Hxb in an interspecific backcross panel, by use of tyrosinase related protein-1, Tyrp-1, whose human homolog maps to 9p13-pter (Abbott et al., Genomics 1991) as a reference locus. No recombinants were identified in 124 animals between Lv and Orm-1. Hxb was found to be 1.6 cM distal to Lv and Orm-1, and 4.8 cM proximal to Tyrp-1, or b. These data therefore contribute to our knowledge of the conserved synteny between HSA 9q and MMU 4.

Comparative mapping of chicken and human genomes is described, primarily of regions corresponding to human chromosomes 1, 4 and 9. Segments of chicken orthologues of selected human genes were amplified from parental DNA of the East Lansing backcross reference mapping population, and the two parental
