Reciprocal cross

Explanation:

a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. In this type of test cross, male of one genotype and female of different genotype are crossed and the opposite is true as well. (i. e the female of one genotype and male of different genotype are crossed.)

As we can see in the male Flagus fly with the Barkus phenotype is being crossed with a female with the wild-type phenotype.

In the second test, we can see that the opposite is true of our first statement where the female Flagus fly has the Barkus phenotype and the male has the wild-type phenotype after being crossed again thereby reversing the genotype.
