Can anyone explain how to calculate the allele frequency of an SNP marker with description: SNP 1 Row Mapping Format: "0" = Reference allele homozygote, "1" = SNP allele homozygote, "2"= heterozygote and "-" = double null/null allele homozygote (absence of fragment with SNP in genomic representation).
And I would be glad if someone explain how to calculate the minor and major allele frequencies a marker and how to calculate with these 1,0 and 2. I searched on many and each and every formula written in the R-program code is different. I am using DArTSeq genotyping. Help me please ??
