A plausible explanation is that they originated from a single recombination event and that progenies of the recombinant diverged subsequently.
The putative PTH1R/PTH3R gene precursor and PTH2R gene are suggested to have emerged earlier, prior to or at the origin of vertebrates (1R), and PTH1R and PTH3R genes diverged subsequently prior to the Chondrichthyes (cartilaginous fish) radiation (2R).
Such an outgroup may diverge from the ABC ancestor before the duplication (Figure 1b) or may diverge after the duplication and subsequently lose one duplicate copy (Figure 1c e; if the outgroup retains both duplicates, the gene will be recognized as not a one-to-one ortholog, and should be discarded).
Thus, we predict Mga rapidly diverged after duplication of a Max or Mlx network member and was subsequently conserved.
torreya and M. coreyi; M. fluviatilis, M. jenkinsi, M. foliata, and M. neilyoungi) appear to have diverged and subsequently expanded their ranges into the Southern Coastal Plain of the Gulf of Mexico with further expansion eastward and northward.
As will be discussed below, sequences that are homologous can diverge and subsequently evolve convergently affecting reconstructed tree topologies.
Subsequently, we will review some sexual selection models of speciation, where Fisherian runaway selection leads to diverging preferences and subsequently to prezygotic isolation.
Subsequently diverging priorities, often driven by changing funding opportunities, created tensions.
We propose that an Anas-like duck split into multiple sister morphs sympatrically and simultaneously at that time, subsequently diverging by assortative mating.
The use of the matK consensus initiation codon for translation in the first diverging subfamily Apostasioideae and in the closely related sister families, and the prevalence of the aic for MatK translation in the subsequently diverging subfamilies (Fig. 6) provides unequivocal evidence for the evolution of the alternative initiation codon within the orchids.
