The variability of characters within populations is generally measured as a function of the character variance, although questions of nongeographic variation are addressed as tests of mean differences ...

I have recently mentioned an analogy between the heritability of height & weight. That is, the proportion of variance of the trait which can be explained by variance in the genes. How closely do ...

This article looks at a simple structured approach to assigning variance contributions and to assuring that the analytical procedure is fit for purpose. The ...

This article proposes a new parameter, the group or class dominance probability, to measure the relative importance of random effects in one-way random effects models. This parameter is the ...

Genetic interactions arise when the joint effect of alleles at two or more loci on a phenotype departs from simply adding up the effects of the alleles at each locus. Many examples of such ...
