However, the genes for lint colour are found to be pleotropic that means they control more than one trait (Murthy 2001), and seed cotton yield and fibre quality are controlled by polygenes and highly influenced by the environment (Magadum et al.

Higher genetic variability with least environmental effect is considered in the selection of genotype but it is difficult when the traits are controlled by polygenes. In this case heritability coupled with genetic advance is the more useful measure for selecting the best individuals [5].

Pre-eminent are the findings from the huge PGC2 collaborative molecular genetic study of almost 37,000 patients with schizophrenia and 113,000 healthy controls which demonstrated that 108 loci are significantly associated with schizophrenia, [4] and that risk is influenced by a much greater number of genes (polygenes) of even smaller effect.

In fact, in NOD mice, diabetogenesis is under complex polygenic control and the penetrance of these polygenes is greatly conditioned by wide disparate conditions (microbial and physical environment, diet, etc.): some environmental pathogens may even offer more protection to NOD mice against the T1D onset, by the simple activation of their immune system [28].

In brief, SOLAR incorporates the information contained in participant pedigrees to obtain maximum likelihood estimates for the proportion of unexplained variance due to additive genetic effects from polygenes ([[delta].sup.2.sub.g]) and the proportion of variance due to unmeasured environmental covariates, measurement error, and nonadditive genetic effects ([[delta].sup.2.sub.e]).
