Use this document to report your findings from the FlyLab Exploration Experiment. The lab report consists of three sections: Data, Exploration, and Lab Summary.
Data: copy any data, graphs, charts, or notes that you have saved in your FlyLab online notebook into this section.
Exploration: Answer the questions. The questions in the Exploration section are the same questions in your FlyLab instructions.
Lab Summary: Write a 100- to 200-word summary.
Data
To copy your data from your online notebook into this section, click on Export Notes and then copy and paste your data into this section. You must disable your pop-up blocker before exporting. Identify each set of data with a title.
Exploration
Answer the following questions in fewer than 100 words:
1. Describe the phenotypes that you observed in the F1 cross.
2. The phenotypes I observed in the F1 cross was the reddish eyes that came from the “wild type” father. This is because “wild type” trait is dominant. So the “brown eye” trait does not show in the offspring. In addition, the “wild type” body color from the mother was dominant, so this is what showed in the offspring, instead of the “ebony” coloring from the father.
3. Describe the phenotypes that you observed in the testcross.
In the test cross there were 4 different types of offspring, approximately equal in ratio. Wild type, Brown eyed, Ebony bodied, Brown eyed with ebony bodies
4. What was the phenotypic ratio for the offspring resulting from this testcross?
The ratio for the offspring of this testcross is 1:1:1:1. See above.
5. Based on this phenotypic ratio, was the F1 wild-type female homozygous or heterozygous for the eye color allele? Explain your answer.
The F1 wild-type female had a heterozygous eye color allele. This is why she had offspring of different types.
6. Based on this phenotypic ratio, was the F1 wild-type female homozygous or
