WebSince T. turgidum is older than T. timopheevii, the B genome has diverged more from the S genome of Ae. speltoides than the G genome. The G genome is virtually identical to the S genome at the molecular level but it differs from it, as well as from the B genome, by major structural chromosome rearrangements. WebMay 1, 2024 · In the most likely scenario, Ae. mutica, but not Ae. speltoides, hybridized with the ancestor of the A clade to give rise to the ancestor of the whole D clade, with a proportion of the A clade ranging from 0.35 to 0.58, suggesting a rather symmetrical hybridization ( Fig. 4 and text S4).
