Linkage between the porcine genes encoding immunoglobulin heavy‐chain allotypes and some serum α‐protease inhibitors: a conserved linkage in pig, mouse and human

Abstract
Linkage between the genes coding for immunoglobulin heavy-chain allotypes and some serum .alpha.-protease inhibitors was demonstrated in pigs by means of segregation data in families. A recombination frequency of about 8% was estimated. This represents evolutionary conservation of an autosomal linkage group as linkage between the homologous loci has previously been reported, in humans and in mice.
