You perform a cross to measure the recombination rate between the G, H, and I genes. Based on the recombination rates, you expect to observe 24 double recombinants, but you only observe 16. What is the coefficient of coincidence (c)?a. 1.50b. 0.40c. 0.67d. 0.60e. 0.33

Answer:

c. 0.67

Explanation:

The coefficient of coincidence is calculated as the ratio of observed double recombinants to expected double recombinants. It's a measurment of how likely a crossing over is to occurr if another one happened nearby. It goes from 0 to 1, and the smaller it is, the less likely are double crossovers to occur.

[tex]Coefficient\ of\ coincidence = \frac{observed\ number\ of\ double\ recombinants}{expected\ number\ of\ double\ recombinants}  \\Coefficient\ of\ coincidence = \frac{16}{24}  \\\\Coefficient\ of\ coincidence = 0.67[/tex]
