  • Most of the size difference between the diploid species occurred prior to polyploid divergence and was largely attributable to TE amplification in the A/AT genome. (edu.sa)
  • After separating from the true parents of the polyploid genomes, both diploid genomes experienced slower sequence gain than in the ancestor, due to fewer TE insertions in the A genome and a combination of increased deletions and decreased TE insertions in the D genome. (edu.sa)

  • In general, there has been a propensity toward growth of the diploid genomes and contraction in the polyploid. (edu.sa)
  • Small indel data for the diploids suggest the possibility of a bias as the smaller genomes add less or delete more sequence through small indels than do the larger genomes, whereas data for the polyploid suggest increased sequence turnover in general (both as small deletions and small insertions). (edu.sa)
