[The genetic differentiation of sheep with different types of wool]. / Geneticheskaia differentsiatsiia ovets s razlichnymi tipami sherstnogo pokrova.

The comparative analysis of the genetic structure of fine-wool, semi-fine-wool, and semi-rough-wool sheep breeds for 8 polymorphous genetic-biochemical systems (Hb, LDR, PN, ME, EST, Dp, Tf, LAP) was carried out. The interbreed, breed and intrabreed differentiations by the polymorphism for genetic-biochemical systems were described. The interrelations between the variability of wool characteristics and the genetic structure of ME and Tf loci, repeated in different sheep groups, were revealed. The "linkage disequilibrium" between ME and Tf loci was detected. The possible mechanisms of the involvement of polymorphous genetic-biochemical systems into selection processes based on the complex of important economical traits were discussed.
