With the molecular markers of random amplified polymorphic DNA ( RAPD ), the genetic distance between sex determination locus ( x ) of honey bee and the sequence tagged site ( STS ) for low brood viability locus was estimated at 1.6 cM. RAPD分子标记在蜜蜂遗传育种中得到较广泛应用.利用RAPD分子遗传标记,估测蜜蜂性别决定位点(x)与低幼虫存活率位点的标记序列位置(STS)之间的遗传距离为1.6cM;
