: Inherited independently of the ABO group, where Rh+ is dominant over Rh-. 2. Determine Joseph's genotype

Before diving into the pedigree, we must establish the rules of the game. Blood typing is governed by three alleles: A, B, and O. lab activity blood type pedigree mystery answer key upd

Many updated labs include the Rh factor (+/−) as an additional layer. The key explains that Rh-positive is dominant (Rh+/Rh+ or Rh+/Rh−) and Rh-negative is recessive (Rh−/Rh−). This simulates more realistic forensic genetics, where multiple markers increase certainty. : Inherited independently of the ABO group, where

Since Joseph’s specific genotype is often a "mystery" in the lab, use his children’s blood types to deduce it. If Rita is Type AB ( cap I to the cap A-th power cap I to the cap B-th power ) and they have a child who is Type O ( Blood typing is governed by three alleles: A, B, and O
