LAB ACTIVITY 2 INHERITANCE OF THE CORN COLOR AND CORN TEXTURE GENES The corn used for this experiment F2 was obtained when purple and smooth textured corn of the F1 generation were crossed with each other The F1 corn was obtained by crossing true breeding purple smooth textured corn with true breeding yellow rough textured corn In this exercise you will be given a corn cob and you will count the number of corn kernels that have the following phenotypes purple smooth purple rough yellow smooth and yellow rough The corn kernels represent the individuals of the F2 generation From this experiment you will be able to determine how the corn texture and corn color traits are inherited 7 Write a hypothesis about how you think these traits are inherited in your statement include whether these traits are inherited according to Mendel s laws and which phenotypes are dominant vs recessive 8 Write a statement if then predicting your results based on your hypothesis hint in your statement predict what the phenotypic ratio will be based on your hypothesis 9 In the table below record the number of corn kernels that are smooth and yellow smooth and purple rough and yellow and rough and purple Note These are your observed values Table 5 Number of kernels Texture Purple smooth Purple rough Yellow smooth Yellow rough Total Number of kernels 44 id 24 IDE 10 Compare your observed and expected results doing the Chi square test Table 6
