Coefficient Of Coincidence Calculator

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.
