In this activity, students must construct a pedigree based off of a story problem. Students read a paragraph about a family with freckles, and they must draw an appropriate pedigree and answer analysis questions.
The pedigree consists of four generations, and students will use symbols such as deceased, unknown trait, and even the symbol for twins. There are seventeen total people in this fictitious story but that could easily be modified through Word.
There are several analysis questions included in this activity, as well. The questions ask students about the pedigree they made, and it also causes students to think critically by asking questions such as family relationships, genotypes, and dominant/recessive traits.
I use this activity as a graded formative before a test, but this could easily be used as a summative assignment, graded homework, etc.
I've included the answer key to the pedigree and analysis questions as well as the rubric I use when I grade their pedigree. The document is in Word to make editing possible. Thank you!
