Corn stocks showing virus-induced aberrant ratio (AR) at the "A" locus were found to have recessive alleles at the R and/or C loci. Since by the known pedigree these loci should be homozygous dominant, the results suggest an inactivation of maize genes by a mechanism as yet unknown. The presence of recessive alleles at these additional loci can explain the segregation ratios obtained in these particular stocks.
在“A”位点表现出病毒诱导异常比例(AR)的玉米株系被发现其R和/或C位点存在隐性等位基因。由于根据已知谱系这些位点应该是纯合显性的,这些结果表明玉米基因通过一种未知机制失活。这些额外位点上隐性等位基因的存在可以解释在这些特定株系中获得的分离比例。
