Genes located on these chromosomes do not assort independently of sex and are said to be sex-linked.
這些染色體上的基因不能離開性別而自由組合,稱為性連鎖。The ms188 gene was finely mapped. a total of 8 new indel markers were designed to map msl88 using a segregating population with a total of 2135 male sterile progenies. ms188 was finally mapped to a region of 95. 8kb between the molecular marker mda7 and k24c1
在與ms188連鎖的分子標記mc015附近設計了8個indel分子標記,對遺傳群體中2135株不育植株進行基因型分析,最後將目的基因定位於第五條染色體分子標記mda7和k24c1之間95 . 8kb的區間內。It is almost certain that the two genes are linked on the same chromosome.
那麼可以認為這兩個基因必定連鎖在同一染色體上。Using these ssr markers and hmw - gs markers, we detected the polymorphism of 111 lines selected randomly from 131 lines of ril - 8. a marker genetic linkage map with 18 chromosomes and 51 polymorphic sites covered 1296. 7 cm of wheat genome was carried out using mapmarker / exp 3. 0
利用上述標記,對隨機選擇的ril - 8群體的111個系進行了分析,採用mapmarker exp分析軟體,繪制了一張共包括18條染色體(不含1a 、 3a 、 7d ) 、 51個位點的分子標記連鎖遺傳圖譜,總長1296 . 7cm 。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。In diploxylon pines, 18s and 5s rdna usually locate on the same or opposite arm of the same chromosome
雙維管束亞屬植物中, ss與18srdna連鎖在同一染色體的同一臂或兩條臂上。分享友人
