    Chickens productivity selection affects immune system genes by А. М. Borodin, Ya. I. Alekseev, K. E. Gerasimov, N. V. Konovalova, E. V. Тerentjeva, D. N. Efimov, Zh. V. Emanuilova, L. I. Tuchemskiy, A. A. Komarov, V. I. Fisinin

    Published 2020-12-01
    “…It can be assumed that the fixation of the allele in the DMA gene (SNP Gga_rs15723) is associated with artificial or natural selection, consistent in broilers and layers. Changes in the loci Gga_rs16057130 and Gga_rs15788101 in the B5 line of the Smena 8 chickens are most likely associated with artificial selection of broiler productivity traits, which can subsequently lead to fixation of alleles at these loci. …”
