SELECTION FOR BEHAVIOR AND CORRELATION WITH THE MACROGLOBULINE AND LYPOPROTEINE SYSTEMS IN THE AMERICAN MINK (NEOVISON VISON)

Abstract

Genetic comparison was performed between mink populations with tame and aggressive behaviour. Six allotypes of the Lpm system; the А1М alpha macroglobulin; and two allotypes of the Ld system, homologue of APOB low-density lipoprotein, were analyzed. The populations differed in markers Lpm1, Lpm3, Lpm5, and Lpm10. Alleles with allotypes Lpm1 and Lpm3 were significantly associated with aggressive behavior, and allele Lpm non-10, with tame behavior. No statistically significant differences were found in frequencies of the Ld1 and Ld2 allotypes of the Ld low-density lipoprotein system.
