AB  - Maize meiotic mutant desynaptic (dy) was tested as a candidate recombination 
      modifier gene because its effect is manifested in prophase I. Recombination rates 
      for desynaptic (dy) and its wild type were compared in two ways: (1) segregation 
      analysis using six linked molecular markers on chromosome 1L and (2) cytogenetic 
      analysis using fluorescence in situ hybridization (FISH)-aided meiotic 
      configurations observed in metaphase I. Chromosome 1L map lengths among the six 
      linked markers were 45-63 cM for five F2 dy/dy plants, significantly lower than 
      the wild-type F2 map distance of 72 cM. Chromosomes 2 and 6 were marked with rDNA 
      FISH probes, and their map lengths were estimated from FISH-adorned meiotic 
      configurations using the expectation-maximization algorithm. Chiasma frequencies 
      for dy/dy plants were significantly reduced for both arms of chromosome 2, for 
      chromosome arm 6L, and for eight unidentified chromosomes. There was a notable 
      exception for the nucleolus-organizing region-bearing arm chromosome arm 6S, 
      where dy increased chiasma frequency. Maize meiotic mutant desynaptic is a 
      recombination modifier gene based on cytogenetic and segregation analyses.
