Following a mutagenesis experiment to identify novel genes affecting the circadian clock in Drosophila melanogaster you discover several mutants. You start considering two of those mutants that you call c and d. The two homozygous c/c and d/d are arrhythmic (arrhythmic is the definition of their phenotype), whereas the two heterozygous C/c and D/d are rhythmic (rhythmic is the definition of their phenotype) with a 24h period. You make two true-breeding stocks: stock 3 homozygous for

Comparing the number of flies expected for the Parental and the Recombinant genotypes, what can be concluded about the C and D loci? Select only one answer.
| 1. |
The Parental are much more than the Recombinant, C & D are linked |
|
| 2. |
The Recombinant are much more than the Parental, C & D are linked |
|
| 3. |
The Recombinant are much more than the Parental, C & D are not linked |
|
| 4. |
The Parental are much more than the Recombinant, C & D are not linked |
|
| 5. |
The Parental are equal to the Recombinant, C & D are not linked |
|
| 6. |
The Parental are equal to the Recombinant, C & D are linked |
