Intra-interval interference.

a, bCorrespond to the data obtained for two independent experiments for intervals I5a and I5b.cOnly four-spore viable tetrads were considered. They correspond to 97% of the tetrads (n = 3,756) in wild type and 10% (n = 5,973) for axr1.dThe IR compares the genetic size of the first interval when a CO occurs in the adjacent interval to the genetic size of the same interval when no CO occurs in the adjacent interval (Table S4A).eThe p values indicate significant differences between axr1 IR and wild-type IR for a given pair of intervals.fThe p values indicate significant differences between IR and 1.
