  1. Math and Mendel Objectives: Review Genetic Inheritance Learn about converting between fractions, decimals and percentages

  2. Step 1: Fill in the following punett squares Father B b Father B B Father b b Mother b B Mother b B Mother b B

  3. Father B b Father B B Father b b Mother B B Mother B B Mother B B

  4. Father B b Father B B Father b b Mother b b Mother b b Mother b b

  5. Step 1: For each of the punett squares, find the fraction of offspring that will have only dominant, only recessive, and both recessive and dominant genes 1 Only dominant 4 Father B b 1 Only recessive 4 Mother b B 2 Recessive and dominant 4

  6. Father B B Only dominant 4 Mother b B Only recessive 4 Recessive and dominant 4

  7. Father b b Only dominant 4 Mother b B Only recessive 4 Recessive and dominant 4

  8. Father B b Only dominant 4 Mother B B Only recessive 4 Recessive and dominant 4

  9. Father B B Only dominant 4 Mother B B Only recessive 4 Recessive and dominant 4

  10. Father b b Only dominant 4 Mother B B Only recessive 4 Recessive and dominant 4

  11. Father B b Only dominant 4 Mother b b Only recessive 4 Recessive and dominant 4

  12. Father B B Only dominant 4 Mother b b Only recessive 4 Recessive and dominant 4

  13. Father b b Only dominant 4 Mother b B Only recessive 4 Recessive and dominant 4

  14. Step 3: For each of the punett squares convert the fractions into decimals then into percentages 1 Father B b Only dominant = .25 = 25% 4 1 Only recessive = .25 = 25% Mother b B 4 2 Recessive and dominant = .5 = 50% 4

  15. 2 Father B B Only dominant 4 0 Mother b B Only recessive 4 2 Recessive and dominant 4

  16. 0 Father b b Only dominant 4 2 Mother b B Only recessive 4 2 Recessive and dominant 4

  17. 2 Father B b Only dominant 4 0 Mother B B Only recessive 4 2 Recessive and dominant 4

  18. 4 Father B B Only dominant 4 0 Mother B B Only recessive 4 0 Recessive and dominant 4

  19. 0 Father b b Only dominant 4 0 Mother B B Only recessive 4 4 Recessive and dominant 4

  20. 0 Father B b Only dominant 4 2 Mother b b Only recessive 4 2 Recessive and dominant 4

  21. 0 Father B B Only dominant 4 0 Mother b b Only recessive 4 4 Recessive and dominant 4

  22. 0 Father b b Only dominant 4 4 Mother b b Only recessive 4 0 Recessive and dominant 4

  23. Additional Material • In order to teach fractional addition along with conversion: • Add up all the fractions for each of the three cases • Then, find the decimals and percentages from the totals • Further fractions can be created by calculating what the chances are that a particular parent will have a particular offspring
