【摘要】 利用已知丝素基因和丝胶基因的克隆片段（ｐＦｂ＿（１００），ｐＳｒ＿（１００））为探针和１２个限制性内切酶，对家蚕基因组ＤＮＡ进行了限制性片段长度多态性分析。结果表明，其ＤＮＡ多态性可用作家蚕基因图谱的分子标记。更多还原

【Abstract】 The clones of fragments of fiborin gene(pFb₁₀₀)and sericin gene(pSr₁₀₀)wereuse.d as probes in this work.Silkworm genomic DNAs were digested with twelve restriction enzymes and the Southern hybridization was carried out with the probes,The resultsindicated that the restriction fragment length polymorphic DNA could be served as the molecular mcqrkers in silkworm gene map conatruction更多还原
