In these crosses, the TM6 chromosome was identified by the Stubble marker. Consequently, the experimental genotypes could be distinguished from balanced heterozygotic flies by absence of the Stubble marker. The expected Mendelian ratio of non-Stubble to Stubble flies was 1:2 since TM6/TM6 and CyO/CyO are embryonic lethal and Su(var)2-5⁰⁴/Su(var)2-5⁰⁴, Su(var)2-5⁰⁵/Su(var)2-5⁰⁵, and Su(var)2-5⁰⁴/Su(var)2-5⁰⁵ die before or at the third instar larval stage. The percentage of expected genotypic ratios was calculated as observed non-Stubble flies × 300/total observed flies.
