Fig. 3. Correlating a spectrum of phenotypes. A set of 14 phenotypes for
eight genes is indicated by the presence (blue) or absence (yellow) of the
phenotype. In this example, genes A and B are perfectly correlated (14 of 14
phenotypes), genes C and D are tightly correlated (12 of 14 phenotypes), and
genes A-D are more correlated with each other than with E-H. This data
representation allows genes and phenotypes to be clustered and calculations of
pairwise correlation coefficients to be made.
