I had computed the HWE test using the --hardy command of the plink 1.9 program, to find the observed and expected heterozygosity. The observed and expected homozygosity has been calculated using the --het command of plink 1.9. Theoretically, the sum of observed homozygosity and observed heterozygosity should give one. However, my finding doesn't fit. Please can I get some justification? Is it possible to happen?
Thank you in advance.
