Hi everyone

I need to understand Minor allele frequency

A SNP with a allele (G) frequency of 0.40 implies that 40% of a population has G allele versus the most common allele (major allele), which is found in 60% of the population.

If a SNP allele frequency is 0.05 how will be calculate its percentage in the population

Please explain with calculation

Regards
If a SNP allele frequency is 0.05 in a population of 100 people:

Total number of alleles for each SNP: 100 * 2 = 200 (each individual has two alleles)

Total number of alleles for your SNP with a MAF of 0.05: 200 * 0.05 = 10

The minor allele is present ten times in your population. However, you don't know how many heterozygote and homozygote.
