Genetics Study Guide
The “poker chip” lab referenced in #2 obviously refers to an exercise involving independent assortmet.  Two jars = two parents.  I don't have a copy of the lab any longer, but it isn't difficult to come up with a similar activity.  I do not have the pedigree in the last question.  However, many of these are available in genetics texts and on-line.
1. Why was it important that Mendel used statistics in his experiments with pea plants?

 
 
 
 
 

2. Why did you use two jars in the “poker chip” lab?
 
 
 
 
 
 

3. What is independent assortment?  Why is this benficial?
 
 
 
 
 
 

4. Which can you see, the genotype or the phenotype?  Explain.
 
 
 
 
 
 
 

5. Why is it important to study genetics?
 
 
 
 

6.  What is crossing over and when does it occur?
 
 
 
 
 
 
 

7. Why are half of all children male?  Explain in relation to mitosis.
 
 
 
 
 
 
 

8. What ratio of children would have brown eyes is you crossed 2 people who were heterozygous for brown eyes?  SHOW PUNNET SQUARES OR YOU WILL NOT RECEIVE CREDIT!!!
 
 
 
 

9. A man has type AB blood and his wife has type B.  Her baby has type O.  Could her husband be the father?  Explain your answer.  SHOW PUNNET SQUARES OR YOU WILL NOT RECEIVE CREDIT!!!
 
 
 
 

10. Examine the pedigree below.  Is this trait dominantly or recessively inherited?  Label each individual with his/her genotype.  Use “E” for the dominant allele and “e” for the recessive.
