Ploidy and gene ontology analysis of chromosome 31. From the 41 CL Brener chromosomes, chromosome 31 was the only one that was supernumerary in all the studied strains based on the SCoPE analysis (a). The ploidy of chromosome 31 from each strain, estimated by the ratio of the alleles in the heterozygous SNP positions, classifies Arequipa, Colombiana, Sylvio, Esmeraldo and Y as tetraploid and 231 as triploid (b). Gene ontology analysis shows that this chromosome is enriched in genes involved in the glycosylation and glycoprotein biosynthetic processes (c)
