[The association of genetic markers in two related swine breeds].
The combinations of genetic markers (allotypes, blood-group systems, and polymorphic proteins) were analyzed in pigs of two phylogenetically related Siberian populations: the newly selected Siberian specialized meat breed SM-1 (daughter breed) and the reproductive core of the Kemerovo breed (maternal breed). Statistically significant interlocus associations were found between the genetic markers that are known not to be linked, being assigned to different linkage groups, and the main selected meat-productivity traits. Some of these associations were shared by both breeds; others were found to be specific to either maternal or daughter populations. Possible genetic mechanisms underlying these associations and their significance are discussed.
