Table 1 Formulae for the expected numbers of triplets WM(Δ) of each type Δ, by branching model M

From: Distinguishing successive ancient polyploidy levels based on genome-internal syntenic alignment

Model \(M\in \mathscr {M}\)Tripling-Tripling-Doubling-Doubling-
Triplet \(\Delta \in \mathscr {T}\)(3,3)(3,2)(2,3)(2,2)
  1. u= probability that two progeny survive after the first polyploidization event. u= probability that three survive. Similarly v and v are the probabilities that two or three progeny survive, respectively, after the second event
