Final answer:
The Coefficient of Coincidence is a ratio of observed to expected double crossovers in genetic recombination. In this case, with 8 observed and 13.4 expected double crossover progeny, the Coefficient of Coincidence is 0.597.
Step-by-step explanation:
In genetics, the Coefficient of Coincidence is a measure used to determine the extent of interference in genetic crossing over events. To calculate the Coefficient of Coincidence for the given question: For the previous question about interference in Drosophila, the expected number of progeny to have the double crossover was 13.4, but only 8 were produced. What is the Coefficient of Coincidence?, you need to use the formula:
Coefficient of Coincidence = (Number of observed double crossovers)/(Number of expected double crossovers)
For this situation, the expected number of double crossover offspring was 13.4, but we observed only 8 such offspring. Therefore, the calculation would be:
Coefficient of Coincidence = 8/13.4 = 0.597 (rounded to three decimal places)
