  • a In these crosses, the TM6 chromosome was identified by the Stubble marker. Consequently, the experimental genotypes could be distinguished from balanced heterozygotic flies by the absence of the Stubble marker. The expected Mendelian ratio of non-Stubble to Stubble flies was 1:2 since TM6/TM6 is embryonic lethal. The percentage of expected genotypic ratios was calculated as: observed non-Stubble flies × 300/total observed flies.
