Transcribed Image Text:**Genetics of Fruit Fly Crosses**
Consider the data in the following table, derived from crossing a female fruit fly that was heterozygous for the sex-linked recessive loci, cut wings (ct), raspberry eyes (ra), and forked (f) bristles, with a wild-type male. Female progeny were all wild-type. Male progeny are listed below.
| Phenotype | Number of males |
|-----------|----------------------|
| ct ra f | 70 |
| + ra f | 76 |
| + + + | 74 |
| ct + f | 356 |
| + ra + | 345 |
| ct ra + | 3 |
| ct + + | 72 |
| + + f | 4 |
| **Total** | **1,000** |
**Discussion**
To determine the genetic interactions and evaluate linkage, calculate the coefficient of coincidence. The coefficient of coincidence is a ratio that compares observed double crossovers to expected double crossovers.
**Question**
What is the coefficient of coincidence for this cross?
- 0.299
- 0.370
- 0.266
- 0.194
- 0.245
Use the table data to compute expected and observed double crossovers, and choose the correct answer from the options provided.
