From them the application of statistical mathematics to biological problems received a great impetus, and if only for this reason they mark a significant step in the growth of quantitative biology.

The consequences of these interactions will be taken up in the next chapter, as will the effects of linkage.

The effect of the gene difference on the phenotype can be described by two parameters and specified completely if the values of these two parameters are known. In the system adopted by Fisher, Immer and Tedin (1932) and Mather (1949a) one parameter (.) is used to represent the phenot
