Answer:

D) Genes for the two traits are located close together on the same chromosome, and crossing over occurred between the two gene loci.

Explanation:

According to the data shown above, we can see that at the crossing of the two flies the genes for the two characteristics are located close to each other on the same chromosome, and the crossing occurred between the two genetic loci.

As you may already know, a chromosome is a molecule formed by the correlation between DNA and proteins that keep the DNA compacted and prevent it from spreading.

Genetic loci, on the other hand, are regions on chromosomes where a specific gene for a specific trait is located.
