If you're still confused about True Alpha (homozygotic Alpha) vs Sub-Alpha (heterozygotic Alpha), please re-read the EXTRA Episode where Hyungseok explains the genetics behind human hierarchy. Basically, "True Alpha" has double Alpha-gene while "Sub-Alpha" has one Alpha gene and one recessive Omega gene.
