Tanglegram showing phylogenetic trees for the kernel (left tree) and wholemeal flour (right tree) from wheat samples.
The linking lines connect the kernel and wholemeal flour data of the same sample. Entanglement is measured by giving the left tree’s labels the values of 1 till tree size, and then match these numbers with the right tree. Therefore, entanglement value is a measure between 1 (full entanglement) and 0 (no entanglement). A lower entanglement coefficient corresponds to a better alignment.
