Other claims from this paper (5)
- Method / resource The integrated maize map had 1443 markers, including 1155 SNPs, across 1346 cM.
- Observation Nine non-centromeric regions showed suppressed recombination.
- Observation One suppressed region likely contained condensed heterochromatin knobs.
- Observation Recombination variation was highly predictable in pericentromeric and telomeric regions.
- Observation Recombination varied 4.5-fold for the same interval across three populations or knob-containing regions.
