"WebMay 16, 2024 · I got a value which is 0.43 meaning 43% phenotypic variation explained by the SNP. Again, I used another formula which is: 2*f*(1-f)*b.alt^2. Here, f is the minor allele frequency and b.alt is the effect size i.e. beta estimate obtained from GEMMA. This gives me a value of 0.03 meaning 3% variation explained which seems reasonable to me.
