Abstract excerpt
Understanding meiotic and genomic stability in polyploid species is critical for advancing genetic discovery and breeding. Potato (Solanum tuberosum), the third most important food crop globally, is represented by cultivated potato, an autotetraploid with highly heterozygous genomes. Here, we revealed that cultivated potato showed different chromosomal pairing configurations and irregular chromosomal...
