what are the sections on chromosomes? genes or DNA?

A cross was made between two strains of plants that are agriculturally important. One strain was disease-resistant but herbicide-sensitive; the other strain was disease-sensitive but herbicide- resistant. A plant breeder crossed the two plants and then allowed the F1 generation to self- fertilize. The following data were obtained:
F1 generation: All offspring are disease-sensitive and herbicide-resistant
F2 generation: 157 disease-sensitive, herbicide-resistant
57 disease-sensitive, herbicide-sensitive
54 disease-resistant, herbicide-resistant
20 disease-resistant, herbicide-sensitive
Total: 288 Formulate a hypothesis that you think is consistent with the observed data. Test the goodness of fit between the data and your hypothesis using a chi square test. Explain what the chi square results mean.

Reliability and probability in forensic tests are important. When you look at matching a paint chip to a specific car, you are working to increase the probability that the right car matching your paint chip evidence will be found. Reliability means you have practiced and applied the correct procedures and processes for all your evidence testing, and you know you can trust the results. Some forensic tests are more reliable than others, and the best type of test or tests to use will usually depend on the kind of evidence that is present. If all types of evidence were present at a crime scene, which type of test would you choose based on its reliability and probability of accuracy? Identify which test you would choose and provide a detailed argument as to why you feel it has a high level of reliability in comparison to other types of evidence. Your answer should be at least two paragraphs in length and should include solid arguments for your choice. There is no wrong choice, just be sure to provide a convincing argument.
