Q. How to do a Chi Square trouble for the gentics class?
Dr. O. Sophila, a close friend of Dr. Ara B. Dopsis, reviews the F2 results Dr. Dopsis obtained in his experiment with iris plants described in Genetic Analysis 4.3. Dr. Sophila thinks the F2 progeny demonstrate that a single gene with unfinished dominance has produced a 1:2:1 ratio. Dr. Dopsis insists his proposal of recessive epistasis produce a 9:4:3 ratios in the F2 are correct. To test his proposal, Dr. Dopsis examines the F2 data under assumptions of the single-gene incomplete dominance model using chi-square analysis.
Work out this chi-square value.
State the answer using two decimal places.
