On the concept of effective number

Theor Popul Biol. 1991 Oct;40(2):269-83. doi: 10.1016/0040-5809(91)90056-l.

Abstract

A generalized conceptual basis for Wright's notion of effective size is presented. The concept is applied to the calculation of effective numbers based on the rate of change of genetic variability. With particular reference to the inbreeding, the eigen value, and the newly introduced "diversity" effective size, the use of the concept as a means for discrimination between and identification of various effective sizes is demonstrated.
