title: [Polymorphism of prolactin and growth hormone genes in chicken lines of Ukrainian selection].
abstract: Polymorphism of prolactin and growth hormone genes in two Ukrainian breeding chicken lines of meat-laying (G-2) and eggs performance (A) direction of productivity was studied. Polymorphism of the 24 bp insertion/deletion in the promoter region of prolactin gene, SNP in the -2402 position of the prolactin gene, the first intron of the growth hormone gene was investigated. Frequencies of I and D alleles in line G-2 and line A were 0.135, 0.865 and 0.730, 0.270; frequencies of C and T alleles--0.155, 0.845 and 0.745, 0.255; frequencies of A, B and C alleles--0.435, 0.395, 0.170 and 0.670, 0.160, 0.170 respectively. The results indicate that high frequency of I, C and A alleles in line A corresponds to the egg performance direction.
