Fig. 6From: Genetic analysis of infectious diseases: estimating gene effects for susceptibility and infectivityArithmetic mean (AM), geometric mean (GM) and linear approximation of best fitted line. Each line is a function of allele frequency, \(p_{F}\), with input values for \(\varphi_{f}\) and \(\varphi_{F}\) being 1 and 0.6, respectivelyBack to article page
