title: Genetic characterization of highly inbred chicken lines by two DNA methods: DNA fingerprinting and polymerase chain reaction using arbitrary primers.
abstract: Thirteen highly inbred chicken lines were analysed at the DNA level by DNA fingerprinting (DEP) and by polymerase chain reaction (PCR) using random primers. In general, the DFP patterns of individuals within a line were identical. The DFP band-sharing (BS) values among lines from different breeds (Leghorn, Fayoumi, Spanish) ranged from 0.10 to 0.20. The DFP BS values among Leghorn lines from different genetic backgrounds ranged from 0.42 to 0.79. The DFP BS values among lines selected for different major histocompatibility complex serotypes from a common genetic background ranged from 0.70 to 0.95. Some randomly amplified polymorphic DNA (RAPD) PCR products were specific to a single line, some to all lines from the same genetic base, and some to all lines from the same breed. The RAPD-PCR band-sharing values ranged from 0.66 to 0.99 for all between-line comparisons. Thus, the ability to detect biodiversity at the DNA level was greater in this study for DFP than for RAPD-PCR. The possible origin of line-specific bands, relative advantages of detecting biodiversity by using different molecular screening techniques and uses of highly inbred chicken lines in molecular analysis are discussed.
