Multilocus genetic analysis of two-breed chicken hybrids

Abstract. Background. Due to the fact that now many new forms of poultry are created by crossing existing breeds and populations, a comprehensive genetic analysis hybrid chickens as ground for further breeding work is particular importance. Aim. To study features population organization genomes inter-breed chicken hybrids. Materials methodology. The experimental was based on use an oligonucleotide probe (GTG)5, which labeled with digoxygenin. hybridized genomic DNA nylon filter, then fragments were visualized using streptavidin-alkaline phosphatase conjugate chemistry. number distribution highly specific each individual. These parameters under include similarity coefficient (BS), distances between groups (D) average heterozygosity levels (H). Scientific novelty. For first time, marker characterizing individual birds have been identified; these can be used in certification populations. novelty also lies determination main characteristics chickens, will consolidate desired traits. Results. Based data obtained, it concluded there relatively small differences various forms, result same source breeds. Brahma × Sussex Light Uzbek Game Amrock hybrids distant from other (D = 0.070).
