    If I understand snps correctly, they should have two alleles ... as in T/T or A/G, etc.

    What does it mean on my 23andme report if it shows only one allele for a particular snp? (just one T on MAOA, for example)

    It means you're a guy :D

    MAOA is on the X chromosome, so you only get one copy.
