In this lab activity, students will solve a theft crime using their knowledge of pedigrees and the inheritance of traits (like ear lobe attachment and blood type) to create a pedigree of a mystery family. They will then determine the genotypes of the family members in order to identify the thief. At the end of the lab activity, students will answer questions about their findings and defend their answers with evidence and reasoning.

*NOTE* Do not purchase if you have already purchased my Heredity Unit Bundle or Biology Complete Curriculum Bundle because you already have this product!

How can I use this?

      • Practice for mastery of blood type, pedigrees, and basic inheritance patterns

      • Fun review activity of multiple heredity topics to tie up your heredity unit

What is included?

  • 1 pages of teacher implementation notes (PDF)
  • 3 pages of student handouts (PDF)
  • A paperless digital version of the student handouts that can be accessed in Google Drive™ (and then downloaded and imported to Microsoft OneDrive™)
  • Answer Key (PDF)
  • Editable template of the first page of the student handouts so you can customize the mystery scenario to take place where you live! The kids LOVE when this is personalized! (.pptx)

How much class time will this take?

For the average student this takes 50 minutes to 1 hour. Advanced students will finish more quickly, so it is encouraged to have an additional activity for those who finish 5 or 10 minutes early. Check out my Heredity Taboo Cards as a great option for fast finishers!

Is this aligned to Next Generation Science Standards*?

YES! Specifically, it is aligned with HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
