Multiple supernumerary chromosomes in the pseudogamous parthenogenetic flatworm Polycelis nigra: lineage markers or remnants of genetic leakage?

abstract：:Among 15 wild perennial species of the genus Glycine Willd. subgenus Glycine, G. tomentella is exceptional. It is composed of four cytotypes (2n = 38, 40, 78, 80), is diverse in morphological features, and covers a wide geographical area. The objectives of this study were to uncover the genomic diversity in 78- and 80...
