Draw picture of each cell in space provided.

5. Meiosis Card Sort Questions
Label where crossing over happens.
Label where independent assortment happens.
There are 2 small and 2 large chromosomes in each cell in image 1 and image 7. But they are not the same! Describe the differences.
How does the number of chromosomes compare in cell 1 and cell 11?
There are 4 cells in image 11. What is similar about all 4 cells? What is different?
What do the 4 cells in image 11 become if this happened in a female? In a male?

6. Opening Activity: June 6, 2018
Sorry I am not here today, but you will continue the work on your Chirwibble! Can you figure out how the chirwibble’s traits get passed down to their offspring?
Find your chirwilbble work and draw your chirwilbble on step 1.
Find your chromosomes, whiteboard and pens/erasers so you are ready to start. You will only need TWO sets of chromosomes at your table. Put any extra chromosomes in the bin at the front table.
I can…predict the traits of offspring
Homework:
Test Retake 6/7, 6/8 & 8am.
Inheritance Quiz Monday June 11th

7. Today’s Goals
Use the paper models to see HOW the gametes all end up different (steps 2-5).
Work with a partner. Each table needs to do this twice: once for the mother, once for the father. (half of you will keep track of Mom’s gametes and half you will keep track of Dad’s gametes).
FOLLOW INSTRUCTIONS!!! There are a lot of steps, so you need to read carefully. Have one person in each partnership be responsible for reading the instructions out loud.
Yes on step 3 you will do some cutting and taping as you model “Crossing Over”.
Work on Fertilization and Analysis Questions.

8. Opening Activity: June 7, 2018
If you did not finish Lab 21 yesterday, please continue working now and I will stamp! If you have questions please ask!
If you are done:
Find your initial idea (family tree) and determine what genotype each individual would have.
Pick up a your class questions at front table. Which questions can you now answer?
I can… How can we predict the traits of offspring?
Homework:
Read Intro for Lab #23 & Prediction
Test Retake 6/8 & 8am.
Inheritance Quiz Monday June 11th

9. What can you add to the model?

10. How are genes passed through the generations?

11. Idea Journal

12. So how do we pass on only half our alleles?
Quick recap of meiosis
Lab #22 Predicting Traits

13. Lab #22 Predicting Traits –
Use egg and sperm charts to determine possible genotypes and phenotypes of offspring.
1. Fill out the table in Part 1 of the worksheet
Which finger on top?

14. Look at the cherwibbles!
Focus on the COLOR – what do you notice?
Is it random? Or can we predict the probability a cherwibble will be green or yellow?

15. Parent Genotype and Phenotype
Genotype: Gg
Phenotype: Green G g

16. Possible Offspring Genotype and Phenotype
Genotype: gg
Phenotype: Yellow g

17. Determining offspring genotypes
Remember from meiosis – half the gametes get one allele, half the gametes get the other
So, half get G and half get g G g G G g g

18. Possible Combinations
Mother (Gg)
Father (Gg) G g G g G G g g G G g g G G g G g g

19. Possible Combinations
Mother (Gg)
Father (Gg) G g G g G
GG = green G g
Gg = green G g
Gg = green g
gg = yellow
= non-functional

20. Egg and sperm charts organize all possible offspring combinations
Mother (Rr)
Father (Rr) G g G g x g G G g R G GG Gg r g Gg gg

21. Genotype probabilities Phenotype probabilities
Egg and sperm charts predict probability of all genotypes and phenotypes produced G g GG Gg gg
Genotype probabilities
25% GG
50% Gg
25% gg
Phenotype probabilities
75% green
25% yellow

25. Now your turn!

26. HOMEWORK: Prepare for Lab #23
Read through background information
Make predictions

27. Lab #23 Review the graphs – any relationships to take note?

28. Opening Activity: June 8, 2018
Have Lab #23 predictions ready for stamp.
Pick up Inheritance unit checklist
Question for you. What would be most helpful for you and your learning today:
Do lab #23 - learn about Sickle alleles in populations.
Review the ideas of lab #23 as a group and spend the day working on idea journal, questions and initial ideas.
WRITE YOUR ANSWER (A or B) on ¼ sheet of paper from front table and put into the bin at front table.
I can…Explain why the sickle cell disease is still in the population.
