You perform the three different two-factor crosses (Cross 1: XY and xy, Cross 2: YZ and yz, and Cross 3: XZ and xz). Assume all crosses are between diploid flies homozygous for the alleles of these genes. You observe 7% recombinants in the first cross, 20% recombinants in the second cross, and 13% recombinants in the third cross. if cross between XyZ and xYz leads to which of the followining recombinant with double cross over .
