Abstract
The problem of detection of inbreeding effects by the .chi.2 goodness-of-fit test is investigated. The noncentrality parameter of the limiting .chi.2 distribution is considered as a function of the inbreeding coefficient in 2 models: a gene locus with m codominant alleles and the generalized [human] ABO [blood group] model. Previous results by Ward and Sing [1970] and by Chakraborty and Rao [1972] were based on inadequate statistical reasoning. In the 1st model, the resulting noncentrality parameter is identical with that found by Ward and Sing. For the 2nd model, the limiting noncentrality parameter is zero.
