WebIn addition, whole genome duplications (WGD) and whole genome triplications (WGT) are modelled with an instantaneous duplication (or triplication) of all genes present at the time of event, with a probability of retaining the extra gene (or of retaining one of both extra copies for whole genome triplications).

WebNov 6, 2024 · 1 Introduction. In this era of whole-genome sequencing, many ancient whole-genome duplication (WGD) events have been uncovered across the eukaryotic tree of life (Van de Peer et al., 2024).One of the main approaches for revealing ancient WGDs using genomic data is the construction of whole paranome K S distributions (e.g. Blanc and … WebWhole-genome doubling (WGD) is common in human cancers, occurring early in tumorigenesis and generating genetically unstable tetraploid cells that fuel tumour development 1,2.Cells that undergo WGD (WGD + cells) must adapt to accommodate their abnormal tetraploid state; however, the nature of these adaptations, and whether they … leechburg boys basketball accessories
