Subindividual Variability as an Individual Property: The Haldane-Roy conjecture is verified and extended: individual plants have not only their characteristic means, but also their characteristic standard deviations and characteristic spatial patterns of within-plant variation.
Subindividual Variability as an Individual Property: The Haldane-Roy conjecture is verified and extended: individual plants have not only their characteristic means, but also their characteristic standard deviations and characteristic spatial patterns of within-plant variation.
This chapter articulates subindividual variability as an individual property in the format of the Haldane-Roy conjecture that describes within-plant variability in organ characteristics denoting a significant shift of opinion about the importance of a phenomenon. The verification of the Haldane-Roy conjecture, and its reinforcement by indications of a genetic basis of within-plant variation, should impel us to change the ways in which the individual plant phenotypes are characterized. Within-plant variance should be granted a descriptive value of the phenotype similar to the value traditionally conferred on the within-plant mean of organ trait values. Hence, acceptance of the Haldane-Roy conjecture opens the way to examining variation among characters, among species, and among populations of the same species, also from the perspective of their levels of within-individual variability.
