ON the basis of a serial formation of chiasmata in time beginning from the centromere, the effect of experimental factors on chiasma formation has been interpreted in terms of the two parameters ...

There were significant differences in the mean Xi and XT among karyomorphs (Table 2a).The analysis in M4 showed significant XT differences among karymorphs (Table 2b), with the inversion homozygotes ...

Distribution of chiasmata and bivalents of WT and p35S RCK-RNAi line. (A) Early diakinesis of WT (left) and p35S RCK-RNAi-L12 (right). Reduced chiamasta can be observed.

DAPI staining and fluorescent in situ hybridization (FISH) of metaphase I chromosome spreads were used to count chiasmata on individual chromosome pairs . This indicated a small but significant ...
