Drosophila Crosses Iii Pre Lab Worksheet Answer Key
Drosophila Crosses Iii Pre Lab Worksheet Answer Key - One hindrance to using drosophila, however, is the need to select virgin female flies for crosses. Complete all follow up questions for this cross. When males of this strain are mated to wild type drosophila females with red colored eyes, all of the f1 offspring have red eyes. The genotypic and phenotypic ratios will then be investigated.
