Question
In a certain variety of tomatoes, for one gene, the allele for purple (A) is completely
dominant to the allele for red (a) color. For another independent gene, the allele for
bursting (B) is completely dominant to the allele for remaining intact (b) when ripe.
A plant of genotype Aa Bb is crossed with a plant of genotype AA Bb. The progeny
resulted in the following numbers of observed phenotypes:
60 purple, intact
240 purple, bursting
Based on the expectations for this particular cross, perform a 7 test on your scratch
sheet and refer to the provided chi square table of probabilities to answer the
following questions.
Blank #1: Provide the overall chi square value.
Blank #2: Provide the probability range for the above chi square value.
Blank #3: In no more than three sentences, concisely state an appropriate
conclusion using the terms significant or not significant.
