Locations of seven markers on the second chromosome. The genetic distances are shown by percentage of recombination rate. The locations of a28 and a708 were revealed by in situ hybridization (Chang et al. ; Chang ). The recombination rate statistically indistinguishable from 50% was marked as >50 cM. Black horizontal line shows the second chromosome, and a black oval dot represents the centromere. The black bar indicates In(2L)B
region and D5 is near the centromere. Two markers c4081 and c7198 may be located near or inside the inversion (see text).
