From: Oligo-painting and GISH reveal meiotic chromosome biases and increased meiotic stability in synthetic allotetraploid Cucumis ×hytivus with dysploid parental karyotypes

Fig. 7

Representative abnormal meiotic behavior in S4 generation of allotetraploid C. ×hytivus. a Genomic in situ hybridization (GISH) image showing 19 homologous bivalents at metaphase I, H-subgenome (red) and C-subgenome (green). Six H-bivalents lagged behind C-bivalents (white arrows, partially indicated). b The disjunction of C-bivalents was earlier than that of H-bivalents (white arrow). c Six H-univalents (white arrows, partially indicated) and four C-univalents (yellow arrows, partially indicated). d Two intergenomic bivalents (white arrows). e and f Two examples of lagging H-chromosomes at anaphase I and telophase I (white arrows). Bars = 5 μm
