The **Coefficient of Coincidence** is a metric used in genetics to measure the actual frequency of double crossovers compared to the expected frequency. This calculation is crucial in understanding genetic linkage and interference.

### Calculation Formula

The formula to calculate the coefficient of coincidence is:

\[ \text{Coefficient of Coincidence} = \frac{\text{Observed Double Crossovers}}{\text{Expected Double Crossovers}} \]

### Example Calculation

If the observed number of double crossovers is 5 and the expected number is 10:

\[ \text{Coefficient of Coincidence} = \frac{5}{10} = 0.5 \]

### Importance and Usage Scenarios

The coefficient of coincidence helps geneticists understand how much interference there is in crossover events during meiosis. A value of 1 indicates no interference, while values less than 1 suggest some level of crossover interference.
