Populus trichocarpa Time of divergence 6?7 Ma is the estimated divergence time of the X and Y haplotype in P. trichocarpa, which is much more recent than P. trichocarpa (poplar) and Populus tremuloides (aspen) divergence. In P. tremuloides, there is no XY haplotype divergence in the position of the P. trichocarpa sex-determining region. This suggests different genomic architecture of sex, with at least one turnover. https://doi.org/10.1111/mec.13126
