Group+5+S10

A WebQuest for 7th Grade (Life Science) Designed by Allyson Chee Mo Chen Tracy Seiler
 * WHO IS THE FATHER?**

 **Introduction** (//Section 1 of the Quest//)

Why do we look the way we do? What determines your hair color? Do you have widow's peak? Are your eyes blue, brown, hazel, or green?

You are a genetic analyst. You are trying to determine the paternity of a baby girl using genetics and probability.

 **The Task** (//Section 2 of the Quest//) You have two potential fathers. You will examine the physical appearance and blood types of the baby, the mother, and the potential fathers. You will learn how to use probability to narrow down the candidates and determine WHO IS THE FATHER!

 **The Process** (//Section 3 of the Quest//)

General Instruction
 * 1) First you'll be assigned to a team of 4 students. You will be a team of genetic analysts! You will be working independently and as a group to determine WHO IS THE FATHER.
 * 2) You will be assigned a role as a specific analyst (Analyst I, II, III, & IV). You will be given an individual worksheet for your specific task. You are expected to complete your individual worksheet independently before you rejoin your group.
 * 3) When you have all finished your individual sections, you will answer the analysis questions as a group.

Analyst I & II: Examining Physical Traits
 * 1) Why do we look the way we do? Go to (link) and find out how genetics and heredity determine your physical appearances.
 * 2) Learn about what genotypes and phenotypes are and how they are related (link).
 * 3) Take a look at the genotypes and phenotypes of the baby, the mother, and the potential fathers on your worksheet.
 * 4) Learn how to use a Punnett square (link). Fill out your worksheet. Can you eliminate any of the potential fathers based on phenotypes alone? What is the probability of a potential candidate being the father?

Analyst III & IV: Blood Types
 * 1) Learn about what genotypes and phenotypes are and how they are related ( link ).
 * 2) Learn about the different blood types and how they are inherited (link).
 * 3) The lab has taken a blood sample of the baby, the mother, and the potential fathers. The results are in! Look at the blood type of each individual on your worksheet.
 * 4) Learn how to use a Punnett square (link). Fill out your worksheet.
 * 5) Can you narrow down the candidates using blood type? What is the probability of a potential candidate being the father?

Group Analysis
 * 1) When you have finished your individual sections, answer the following questions.
 * 2) You will compare and contrast your individual results to your group members'. Did your results support or disprove each other's work? Can you determine WHO IS THE FATHER?

 **Evaluation** (//Section 4 of the Quest//)

You will be graded on the completion and accuracy of your answers on your individual worksheet and the group worksheet.

INDIVIDUAL WORKSHEET (graded independently): Your answers should demonstrate your ability to correctly determine genotypes based on phenotypes. You need to accurately label and fill out all the punnett squares provided on your worksheet. Your also need to correctly answer the probability questions using the data gathered from your punnett squares.

GROUP ANALYSIS (graded as a group): You will be graded on the completion of the analysis questions. You need to include evidence from both individual worksheets. Use complete sentences.

 **Conclusion** (//Section 5 of the Quest//) Congratulations! You figured out who the father is. With your expert knowledge as a genetic analyst, you played a crucial role using genotypes, phenotypes, heredity and probability in the determination of the father of this baby. Thank you for your hard work!
