In order to identify DNA variants within the 5'-flanking region of the bovine κ-casein (κCn)-encoding gene, this area of the gene from 13 cows belonging to seven breeds (Holstein Friesian, Brown Swiss, German Simmental, Jersey, Galloway, Scottish Highland and Ceylon Dwarf Zebu) was analysed.

✦ Synopsis
Growth hormone receptor (GHR) has a major role in the regulation of growth hormone action, and thus, is an obvious candidate gene associated with milk production traits in mammals. The present authors have sequenced 273 bp of the 3′ flanking region of the bovine GHR, and found three length variants and one base substitution polymorphism in this region. Allele frequencies of the length variants differ between Finnish native and commercial dairy cattle breeds. The chromosomal localization of GHR was confirmed to bovine chromosome 20 by synteny mapping and linkage analysis.

Southern blot analysis, a restriction fragment length polymorphism in the 3' flanking region of the rabbit 31-globin gene was detected. Two alleles, characterized by 9.7-and 12.4-kb BamH1 fragments and by 15.3-and 18.0-kb HindlII fragments, have been detected in a small population of White New Zeala
The HLA-DQA1 gene exhibits haplotype-specific restriction fragment polymorphisms due to DNA rearrangements. We found that some of these polymorphisms extend into the 5' flanking region of the gene and are distinct from other HLA-DQA1 related DNA polymorphisms so far reported. Sequencing of genomic D
