1. Recombination rates at various locations in the genome.
Recombination rates at various locations in the genome. Red bars are map units per megabase measured within ry at the endogenous location (86E) and at four different ectopic locations. Blue bars are the measured frequency of noncrossover gene conversion events at the same locations. Yellow segments are map units per megabase across a region flanking each site, according to Lindsley and Zimm (1992). The width of these bars is proportional to the size of the region that was used to calculate recombination rates. For 86E, this is 1.75 Mb (kar to cv-c); for 2A, it is 1.16 Mb (su(wa) to pn); for 6E, it is 1.6 Mb (rux to cm); for 20C, it is >2.2 Mb (mal to su(f), which includes an unknown amount of unsequenced heterochromatin); and for 102D, it is 1.35 Mb (the entire assembled euchromatin on 4). The drawings below represent 3R, X, and 4R. Stippled regions are pericentric heterochromatin. Green lines show approximate positions where recombination measurements were made.
