While specific lab versions vary, most "updated" mystery activities follow a similar logic. Here are the likely answers for the standard pedigree markers:
By using this updated framework, you can accurately navigate any blood type pedigree. Remember to always look for the OO and AB individuals first—they are the keys that unlock the rest of the genetic code. lab activity blood type pedigree mystery answer key upd
A pedigree is a visual chart that tracks a trait through generations. In a blood type mystery lab, squares represent males and circles represent females. Lines connect parents and offspring. The goal is usually to identify the blood type or genotype of a "mystery" individual or to prove paternity/maternity within a fictional scenario.

Step 2: Identify the CodominantsNext, locate the Type AB individuals. Their genotype is always AB. These individuals are "fixed points" in your puzzle because there is no ambiguity about which alleles they carry. A pedigree is a visual chart that tracks
A and B alleles are codominant. If an individual inherits both, their blood type is AB. The O allele is recessive. An individual only has Type O blood if they inherit two O alleles. Therefore, the possible genotypes are:Type A: AA or AOType B: BB or BOType AB: ABType O: OO Decoding the Pedigree Mystery
