Mean peak heights per allele will be computed as follows, the peak heights of the two alleles for a heterozygous locus are summed and divided by two while the peak height of a single allele for a homozygous locus is divided by two. Heterozygous peak balance (Hbx) is the ratio of balance between two alleles of a heterozygous locus. Hbx is calculated by dividing the smaller peak height by the larger peak height, resulting in a value that is always less than or equal to one. A value close to one means that the two alleles are balanced.
