For the Y chromosome, since there is only 1 copy of the Y per cell, there should only be one allele for an individual at any location. I don't know why Geno 2.0 reports two alleles for the Y, except for a few locations at which there is an almost identical sequence on the X chromosome,and the Geno 2.0 chip picks up both the Y and X alleles. For all of the autosomes, where there are 2 copies per cell, 2 alleles are expected, and they can be identical or different at any location.
