11. A strawberry farmer determines that the average weight of individual strawberries produced by plants in his garden is 3 g. He selects the 10 plants that produce the largest strawberries; the average weight of strawberries among these selected plants is 6 g. He interbreeds these selected strawberry plants. The progeny of these selected plants produce strawberries that weigh 4 grams.

If the farmer were to select plants that produce an average strawberry weight of 7 g, what would be the predicted weight of strawberries produced by the progeny of these selected plants?

Covid-2019 is a virus dependent pandemic problem in the world. It is more related to the immune system. If you were able to design functional foods, what nutrients would you like to select, and why? Please consider liquid and solid food types and their production process, and benefit for human health.

Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disease that causes cysts in the kidneys that can lead to kidney failure. The most common gene mutated in this disease is PKD1. Imagine that you are researcher working on ADPKD and a doctor has provided you with biological samples from patient with ADPKD. You have been tasked with identifying the mutation in PKD1 and then to test how this mutation affects protein function. Use the links provided to research ADPKD and PKD1 along with what we learned in class to answer the following questions.

1.Design an experiment to test the dysfunction of the mutant protein.

a.What is your hypothesis?

b.What technique would you use and why?

c.What is information would the technique provide?

d.How could your experiment help in the treatment or prevention of the disease?
