  5. Linkage analysis plays an important role in gene mapping. the foundation : the two gene locuses which locate on the same chromosomal ( eg. disease gene and marker gene ) happen to cross over and recombine. the farther the distance between two locuses is, the higher the probability happening to cross over is, the lower the probability that the two locuses are inherited to offspring together is, that is, the degree of linkage is not strong. so we can estimate the distance and the degree of linkage by the recombination fraction between the two locuses to locate gene

    連鎖分析是基因定位主要策略之一，其基本原理是位於同一染色體上兩個基因位點（例致病基因與標記基因）在減數分裂的過程中會發生交換與重組，染色體上的兩個位點間距離越遠，發生重組的概率就越大，兩個位點在一起傳給後代的機會就越少，即連鎖程度弱，這樣由標記位點與疾病位點間的重組率可估算出兩者間的距離以及連鎖程度，達到基因定位的目的。
  6. Pfge analysis of these 21 blocked strains revealed a common chromosomal deletion in the 300kb asel fragment which might be responsible for antibiotic 5102 - iii biosynthesis. so the 300kb fragment was recovered and used as probe to hybridize with 10 - 22 genomic library. cosmids in this region were aligned and suitable fragments in this region were selected and used further for the construction of gene replacement plasmids
