Abstract
The purpose. To study genetic structure of populations of hens of line G2 (Plimutrok Belyi) and line 38 (Rodisland Krasnyi) on locuses MSTN and TLR4. Methods. Polymerase chain reaction — polymorphism of length of destruction fragments. Results. Frequencies of alleles A and G on locus MSTN have made 0,33 and 0,67 in line G2; 0 and 1 in line 38; of alleles A and B on locus TLR4 — 0,3 and 0,7 in line G2; 0,66 and 0,34 in line 38. Conclusions. Gene TLR4 is polymorphic in both lines, and MSTN — only in line G2. On gene MSTN the deflexion from genetic equilibrium in line G2 is fixed. The probed populations are essentially differ on genetic structure on both locuses.


Key words: genetic structure, hens, restriction analysis, gene of myostatinum (MSTN), gene of tall-like receptor 4 (TLR4).
