Question

The expected phenotypic ratio for leaf shape and fruit colour genes is 9:3:3:1, if both genes are on different chromosomes and assort independently during gamete formation. The information below represents two sets of data collected from the above cross. Data Set 1 is from a population of 5000 tomato plants and Data Set 2 is from a population of 50 tomato plants.

Phenotypes	Observed Probabilities
	Data Set 1 (N = 5000)	Data Set 2 (N = 50)
Regular Red	0.58	0.050
Regular Yellow	0.16	0.29
Potato Red	0.20	0.050
Potato Yellow	0.060	0.61

A. Compare both data sets to the expected probabilities. Are there any significant differences between the observed results and the expected results? Explain.

B. Are the genes for leaf shape and fruit colour assorting independently? Explain.
