Transposable elements, or insertion elements, are dna sequences which can be inserted into many different sites in chromosomes . 转位因子或插入因子是能够插入到染色体不同位点的DNA序列。
These were controlled by multiple allels or by loci with allels that segregate independently whereby epistasis also may have played a role . 这些是受复等位基因或含分离等位基因的位点支配的,上位性也可能靠它而起了作用。
The mutations at 16 positions were found for the first time 其中16个突变位点未见过报道。
