Linkage between the loci for serum albumin and vitamin D binding protein (GC) in the Japanese quail

Abstract

Summary Vitamin D binding protein ( GC ) and serum protease inhibitor ( PI ) have been added to genetic markers in the Japanese quail. Both loci were controlled by autosomal codominant alleles named GC A, GC B and PI A , PI B , PI C , respectively. Close linkage between the loci for serum albumin ( ALB ) and GC protein is reported. Two recombinants were observed in 145 informative offspring of 14 families. The recombination frequency between the loci was estimated as 0.014±0.006. Thus, GC was assigned to linkage group II in the Japanese quail. No signs of linkage were observed among the loci for the ALB‐GC complex, PI. serum prealbumin 2 ( PA2 ), phosphoglucose isomerase ( PG1 ), 6‐phosphogluconate dehydrogenase ( PGD ) and esterase‐D ( ESD ).
