WitrynaDNA ploidy, assessed microspectrophotometrically in 143 gastric carcinomas, was correlated with the presence or absence of venous invasion and liver metastasis. Patterns of DNA distribution were grouped into cases of low and high ploidy. The incidence of high ploidy was 61.4% in gastric cancers with … Witrynaploidy populations. Bootstrapping across loci is implemented during Fst calculation to gener-ate conﬁdence intervals and p-values around pairwise Fst values. StAMPP utilises SNP geno-type data of any ploidy level (with the ability to handle missing data) and is coded to utilise multithreading where available to allow efﬁcient analy-

WitrynaPolyploidy is defined as organisms carrying extra sets of chromosomes. That is, more than the normal two sets of homologous chromosomes.
