Whole-genome sequencing and mate pair sequencing of D. melanogaster carrying second (CyO) and third (TM3) balancer chromosomes

We used a Drosophila melanogaster line (a "double balancer") carrying balancer chromosomes for both the second (CyO) and third (TM3) chromosomes. We crossed the double balancer to an isogenic wild-type "virginizer" line to obtain trans-heterozygous adults from the F1 generation. Whole-genome sequencing and mate pair sequencing were used to identify Single Nucleotide Variants (SNVs) and Structural Variants (SVs) on both chromosomes.
