Q. We have a recombinant inbred line population in the F10 generation (NOTE THAT THIS IS A RECOMBINANT INBRED POPULATION (RIL), NOT AN F2 POPULATION). In this population, it was observed that there were 62 RILs with purple flowers and 38 RILs with white flowers.

1. What is the expected number of individuals for each class if a single dominant gene conditions purple flower color? For example, the parents used to produce the RIL population could be WW x ww.

2. Calculate the Chi-square statistic for this expected ratio.

3. Does the observed number of purple vs white fit the expected ratio for a single dominant gene at the 0.05 level of probability?

Why would we choose a cDNA library over a genomic DNA library? In other words, what is the difference between the two?

Find and analyze an article (first published in the last 28 days) about some topic dealing with nutrition and/or exercise addressing a hypothesis. This can come from a newspaper, magazine or other periodical.Analyze the article and address the following:

1. What hypothesis was tested?

2. How was it tested?

3. Was the hypothesis supported or rejected?

4. Is the sponsor of the science mentioned? This could be a university where research was conducted, a company that supplied funding, etc. Do you think the sponsor may have influenced the science? By that I mean do you think the source of funding could lead to a conflict of interest?

5. What are some implications of this research?

6. What could you do if you wanted to find out more about the topic? Be more specific.

You are tasked with providing Flapper evidence of evolution, using examples from biology, and are given unlimited resources to show and tell whatever you would like that helps you explain.What are 2 different types of evidence supporting the evolutionary concept of descent with modification that you would use? Please describe how you would explain them to Flapper, using specific examples.

Compose a short (1.5 – 2.5 page) essay explaining one common alteration in vision and one common alteration in hearing. You should briefly describe the pathophysiologic changes, prevalence, manifestations, and treatment for each. You should also explain the mechanism that the specific treatment uses to return a normal functioning state.
