Abstract:

In estimating the association of weight gain on initial weight, regressions were positive and the correlations significant. Variation in initial weight among tested individuals and groups is expected to bias growth estimates of these groups in programmes of genetic testing, as a result of this association. Obviating this bias requires an adequate correcting technique, involving estimation of an environmentally generated correction factor. Phenotypic regression coefficients may be regarded as maximum estimates. -from Author
