Zinc content in different genotypes of Drosophila melanogaster. (A) Zinc content was measured by atomic absorption spectrometry. white and fbl1, ry506/TM3, ryRK, Sb, Ser (abbreviated fbl1/TM3 throughout the text) were the same stocks as in [20], whereas metal content of fbl1, ry506/TM6, Tb (abbreviated fbl1/TM6, Tb throughout the text) flies was assessed for the first time here. Note that fbl1 heterozygosity does not correlate with total body zinc accumulation. Analysis of Variance indicated significant differences between the genotypes with p < 0.001. (B) Zinc content measured in female and male progeny derived from indicated crosses. Note that male progeny derived from low zinc mothers is also low in zinc, suggesting that the maternal X-chromosome is responsible for the low zinc phenotype. Analysis of Variance indicated significant differences between samples with p < 0.001.
