Need an alternative for GbS or a provider at lower cost.

Need to check if coverage (sequence depth) is enough for variant calling in polyploids?

FASTQ, VCF, Hapmap, DArT single row and two row format, FlapjackMusabase, BTracT, R, Flapjack (Visualisation) GOBII, DNA sample tracking (not specific to polyploids)GATK, Fastx toolkit, Picard tools, Sam tools, VCFtools, BCFtools, PLINK

Tools to manipulate VCF files of polyploids.

Filtering tools (vcf tools) don't work for polyploids

Lindsay recommends an R package - VariantAnnotation (Bioconductor)

Tools for mapping triploids.

Haplotypes reconstruction and inferences


Banana is also multiple ploidy levels (2x,3x,4x). cultivated ones are low fertile and vegetatively propagated. Triploids can be allopolyploid. it makes complex the use of GWAS difficult beyond diploids

Challenge - don’t know the ploidy level for Yam (single dose markers?)
