Intragenomic pairing patterns have been examined in pollen mother cells (PMCs) of high chiasma frequency from C(0) autotetraploids, representing seven diploid Lathyrus species. Six species were known to display intergenomic correlations between numbers of autonomous synaptic sites and the content of...
