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

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 GCA, GCB and PIA, PIB, PIC, 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).
