Leonberger

Placed on this panel from 10 sequenced dogs, among 258 breeds.

Measured nearest to Saint Bernard, and nothing among the other 257 breeds is nearer. The smallest branch holding them both covers 0.7% of this tree.

The 12 breeds nearest to Leonberger.

The line starts at the tightest pairing this panel holds and ends at the widest separation measured on it, so how far along these marks sit is the answer to how close Leonberger really is to anything.

Closeness is measured from the genomes, and nothing else. It has no units and no dates. Two breeds sitting close together means their lines separate late in this data. It does not mean either one came from the other.
