Draw a standard pedigree using these symbols: squares for males, circles for females, and a horizontal line between them to represent a marriage. A vertical line leads down to their children. Place all known family members from the Joseph and Rita family data into this chart, numbering generations (I, II, III) with Roman numerals. by shading their symbols, as this will be crucial for elimination later.

Step 4: Check Parental ConstraintsIf a parent is Type AB, they cannot have a Type O child because they don’t have an O allele to pass down. Similarly, if a parent is Type O, all of their children must carry at least one O allele. The Mystery Answer Key: Common Scenarios lab activity blood type pedigree mystery answer key upd
