Question
Amy conducted an experiment to assess Mendel's law of segregation. A true breeding pea
plant with purple flower is crossed with a true breeding white flower plant. The Fi plants were
self-fertilized to produce two sets of F2 data as shown below:
Set 1
40 purple
9 white
Set 2
400 purple
90 white

(i)
What are the genotypes of the parents and the F, offspring?
Analysc the results for both datascts using chi-squarc analysis. Calculate x valucs,
estimate the p values and make a conclusion for both cases.
(ii)
From the above analysis, what can you conclude about the importance of
gencrating large
(iii)
in cxpcrimental conditions?
