Calculate Minor Allele Frequency
Calculate Minor Allele Frequency. Minor allele frequency (maf) refers to the frequency at which the second most common allele occurs in a given population. By measuring the amount of genetic variation in a population, scientists can begin to make predictions about how genetic variation changes over time.

1 you need to report allele frequencies using plink for some european samples do the same for hispanic samples use a software to subtract the two allele frequencies obtained.
