Genetics • Genotype • Phenotype • Identity • Variation How to grab “Genotype” and “Phenotype” with their “Identity” and “Variation”. One way is to make a catalogue of facts among “them”. The other way is to give a strategy to make the catalogue.
Genotype Phenotype Intermediate phenotype Terminal phenotype

Distance: More than one definition 距離にもいろいろな定義がある
Difference among graphsグラフ間の違い Topology (Shape) and length of edges 位相(形)と辺の距離 Same or different as a tree?
Tree needs “distance” with its definition. Clustering methods also need definition to make tree structure..
Data give trees and change the order in items. When the order in items are not changed and when relation among the items are displayed, it is correlation matrix.
Relations among columns Original data Relations among lines Relations among columns and lines
Chromosomes have two parental chromosomes. But a base has only one parental base.
