The information below represents two sets of data collected from the above cross. 

Phenotypes  Data Set 1  Data Set 2  Regular Red 26  846  Regular Yellow 15  273  Potato Red 6  287  Potato Yellow 12  94  Total 59  1 500 

In the previous question, you determined the expected phenotypic ratio if the genes for leaf shape and fruit colour are on different chromosomes and assort independently during gamete formation. 

Convert the expected phenotype ratio into the expected probability for each of the four phenotypes and record them in the table below. (Record your answers as a value between 0 and 1 rounded to two decimal places.) (1 mark) Data set 1 and 2 are the actual data observed from the cross. Calculate the observed probability of the four possible phenotypes for each data set by dividing the number of progeny in each class by the total number of progeny and record these in the table below. (Record your answers as a value between 0 and 1 rounded to two decimal places.) (2 marks: 1 mark for each data set)

Probability = Number of Progency in Phenotype class  Total Progeny
