I am new to SNPs and the dbSNP database. I am not quite sure if I understand how to find major and minor alleles for a particular position from the database.
Let's take for example rs16532.
Initially, the "Allele" section says that "RefSNP Allele" is C/G. Next, the "Ancestral Allele" is G. Does this mean that the reference allele is G ?
Now we come to the tables on that page. Which of the tables should I refer to, to find major and minor alleles for this position ? There's a "Population Diversity" section which has some statistics. Should I be referring to this table ? Also, how should I find the strand information for the reference as well as the major and minor alleles ?
Also, some more basic questions :
Are major and minor alleles ALWAYS alternate alleles ? Can a minor allele be a reference allele ?
Any help will be greatly appreciated.
