  1. warm-up • On page 99: • How many chromosomes are in each cell at the end of Meiosis II?

  2. Layered Curriculum Wrap up/Test Information • Organize every piece of paper in your folder. • Put each piece of paper in order starting at C1 and going all the way through to the As. (C1, C2, and so on) • If it does NOT have a grade on it, bring it up to me. • Put every grade you got in your packet. If you don’t put the grade in your packet I’m not giving you credit for it. • Do NOT put work that you did not do in your packet… I know what you did and didn’t do… 

  3. By the end of today you will… • Be able to explain how traits are passed from parents to children by creating your own bug.

  4. By the end of today you should be able to answer… • How do humans inherit traits? • How many chromosomes do humans inherit from each of their parents?

  5. Meiosis and Traits • http://player.discoveryeducation.com/index.cfm?guidAssetId=BEC10DB8-4BA2-41DC-A0CF-F782BA9641BA&blnFromSearch=1&productcode=DSC

  6. Procedure for Creating Your Bugs • Group Pairings • Pick one piece of paper out of EVERY one of the 10 bags. • Pink paper = Mom Traits • Yellow paper = Dad Traits

  7. Procedure for Creating Your Bugs • Record your pieces of paper in the first two columns on your data table.

  8. Procedure for Creating Your Bugs • Combine the letters from both the mom and the dad in the “Offspring” column.

  9. Procedure for Creating Your Bugs • Determine what your bug will look like using the following key.

  10. Procedure for Creating Your Bugs • Using the key, write what your bug will look like in the last column.

  11. Procedure for Creating Your Bugs • Once your teacher approves what your bug should look like, you can get materials from the back of the room and create your bug. • You can be creative, but it must follow the traits you said it would look like! • When you are done with your bug, raise your hand and your teacher will tell you what to do with it.

  12. Does everyone’s bugs look the same? • Does everyone’s bugs look the same? • The variety of bugs has to do with the different combinations that you pulled out of the bags. • Not everyone pulled the same traits, so each bug looks different. • Since we all have different parents, all of us look different too!

  13. By the end of today you should be able to answer… • How do humans inherit traits? • How many chromosomes do humans inherit from each of their parents?
