Shorn (shn): a new mutation causing hypotrichosis in the Norway rat

Article Abstract:

A spontaneous hypotrichotic mutant has been discovered in a colony of albino Norway rats. The new mutation, designated shorn (shn), may be independent of previously described hypotrichotic rat mutations. It is possible that the mutation identifies a new gene vital for the normal development or maintenance of a hairy mammalian coat. It will be necessary to undertake further research to establish the phenotypic and genotypic characterization of the shn gene if its normal role in development is to be fully understood.

The 'spotted' locus maps to bovine chromosome 6 in a hereford-cross population

Article Abstract:

A study was conducted to analyze the spotted locus maps to bovine chromosome 6 in a cross population of Hereford. The S locus was mapped by genetic linkage to bovine chromosome 6 between the microsatellite markers ELO3 and BM4528. Two-point analyses were carried out to obtain maximum likelihood estimates. Results indicated that the majority of genes mapped to bovine chromosome 6 also map to mouse chromosome 5.
