[Genetic control over 7 Lpm-system allotypes of very high-density serum alpha2-lipoprotein the mink]

Population and hybridological analyses have demonstrated that the alloantigenic markers of very high density alpha2-lipoprotein of mink serum, Lpm7 and Lpm8, along with Lpm1, Lpm2, Lpm3, Lpm4, Lpm5, belong to a common immunogenetic system. 21 Lpm-phenotypes are determined at least by 36 genotypes; each of the 11 phenotypes is conditioned by a single genotype, each of the remaining 10 are conditioned by 2, 3 or 4 genotypes. The Lpm allotypes and allogroups are coded by the genetic units Lpm8, Lpm4, Lpm4,8, Lpm4,7, Lpm3,4,8, Lpm1,8, Lpm1,2,7, Lpm2,4,5,7, which behave as alleles. The last, six seem to be haploid sets of closely linked genes.
