The quality of plant genome assemblies depends on genome size, ploidy, heterozygosity and sequence coverage, but most NGS-based genomes have on the order of tens of thousands of short contigs distributed in thousands of scaffolds.

From Nature

For example, in the 1980s and 1990s ploidy in neuroblastoma48 and cytogenetic abnormalities in acute lymphoblastic leukaemia49 were used to determine the composition and strength of the cytotoxic chemotherapy required to treat these cancers.

From Nature

The low ploidy and low mutation rate clusters four and five contain many TRU samples, whereas tumours in cluster 6 have comparatively lower tumour cellularity, and few other distinguishing molecular features.
