Linkage of the analbuminemia locus (alb) and the hooded locus in the rat, Rattus norvegicus.

A linkage study of the analbuminemia (alb) with some coat color loci (a,b,c,h) has been carried out by crossing the analbuminemic random-bred mutant NAR strain with the abh tester strain of rats, the Agouti-Irish inbred ACI strain and the Agouti-Nonhooded inbred IS strain. The analbuminemia (alb) locus is not linked to a, b, and c loci but linked to hooded locus from F2 and backcross progeny of the F1 hybrids of abh X NAR, ACI X NAR and IS X NAR to NAR. Recombination value between alb and h was 16.4 +/- 2.3 per cent from the data of F2 and backcross progeny of (ACI X NAR) F1 and (IS X NAR) F1 to NAR. This is the third locus on the sixth linkage group of the rat.
