Math and Mendel Objectives: Review Genetic Inheritance Learn about converting between fractions, decimals and percentages
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
Father B b Father B B Father b b Mother B B Mother B B Mother B B
Father B b Father B B Father b b Mother b b Mother b b Mother b b
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
Father B B Only dominant 4 Mother b B Only recessive 4 Recessive and dominant 4
Father b b Only dominant 4 Mother b B Only recessive 4 Recessive and dominant 4
Father B b Only dominant 4 Mother B B Only recessive 4 Recessive and dominant 4
Father B B Only dominant 4 Mother B B Only recessive 4 Recessive and dominant 4
Father b b Only dominant 4 Mother B B Only recessive 4 Recessive and dominant 4
Father B b Only dominant 4 Mother b b Only recessive 4 Recessive and dominant 4
Father B B Only dominant 4 Mother b b Only recessive 4 Recessive and dominant 4
Father b b Only dominant 4 Mother b B Only recessive 4 Recessive and dominant 4
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
2 Father B B Only dominant 4 0 Mother b B Only recessive 4 2 Recessive and dominant 4
0 Father b b Only dominant 4 2 Mother b B Only recessive 4 2 Recessive and dominant 4
2 Father B b Only dominant 4 0 Mother B B Only recessive 4 2 Recessive and dominant 4
4 Father B B Only dominant 4 0 Mother B B Only recessive 4 0 Recessive and dominant 4
0 Father b b Only dominant 4 0 Mother B B Only recessive 4 4 Recessive and dominant 4
0 Father B b Only dominant 4 2 Mother b b Only recessive 4 2 Recessive and dominant 4
0 Father B B Only dominant 4 0 Mother b b Only recessive 4 4 Recessive and dominant 4
0 Father b b Only dominant 4 4 Mother b b Only recessive 4 0 Recessive and dominant 4
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
