For the first experiment ever on Drosophila mutations. Answer the following questions.
a. What is the title of the first published paper explained the experiment and what is the name of the Author?
b. What is the first mutation discovered in Drosophila?
c. Explain the changes in the Drosophila yellow mutant (Y)compared to wild type.
Suppose that a mutation resulted in a tapeworm that did not have hooks. Assuming this tapeworm was a human parasite, what is the most likely explanation of the effect might this have?
The tapeworm would spread throughout the human body.
The tapeworm would complete its entire life cycle inside the human host.
The tapeworm would not remain in the digestive tract very long.
The tapeworm would not be able to enter the human body.
The tapeworm would reproduce more to compensate for a lack of hooks.

- Use the information provided in the experiment below to annotate/ label the figure. Background: Boll weevil is a serious pest of cotton crop. Effective control involves applications of chemical insecticides, increasing the cost of production and environmental pollution. The current genetically modified Bt crops have allowed great benefits to farmers but show activity limited to lepidopteran pests. This work reports on procedures adopted for integration and expression of a cry transgene conferring resistance to boll weevil and fall armyworm by using moleFour Brazilian cotton cultivars were microinjected with a minimal linear cassette generating 1248 putative lines. Complete gene integration was found in only one line (TO-34) containing one copy of crylla detected by Southern blot. Protein was expressed in high concentration at 45 days after emergence (dae), decreasing by approximately 50% at 90 dae.
