An experiment was done to determine the linkage relationship of three genes (a, b, and c) in Drosophila melanogaster.
Homozygous females phenotypically a, c were crossed with homozygous males phenotypically b. The F1 females were all wild-type in appearance and the F1 males were all a, c.
Give the genotypes of the parents? Give the genotypes of the F1 flies and show the genotypic arrangement in the female F1?
