We also talked about directional selection, disruptive selection, and balancing selection. Define these terms, and give an example of each. How are these types of selection similar, and how are they different? Are the traits under selection polygenic, or do they follow mendelian inheritance? What happens to the allelic and genotypic frequencies for each of these as they progress over time?

There are three modes of natural selection: stabilizing selection, directional selection and diversifying/ disruptive selection. Describe each mode and explain how each mode affects the evolution of a population.

How do disruptive selection, directional selection, and stabilizing selection differ from one another?

10. What is directional, stabilizing and disruptive selection and what roles do they play in adaptation and speciation?

10. What is directional, stabilizing and disruptive selection and what roles do they play in adaptation and speciation? 11. What is genetic drift? What role does it play in moving a population from one adaptive peak to a more fit adaptive peak?

(1) (26 pts) In lecture we talked about how demographic forces and natural selection can affect patterns of polymorphism (i.e. genetic variation within species). (a) Describe 2 patterns in genetic variation data (e.g. polymorphism data) that can be caused by balancing selection. (b) List three ways a bottleneck can affect genetic variation. (c) Describe 2 approaches one can use to distinguish bottlenecks from selection scenarios at generating the pattern in the data.

We talked about HLA genes in autoimmune diseases. However, HLA typing is also important in immunity with respect to organ and blood matching. Discuss the genetics of HLA typing. If genetic matches are best found among close relatives, how is it possible that matches for organs can be found in unrelated individuals?

This week we are learning about atomic physics. At some point we talked about photons. Do some research about photons and share your findings with your group about photons, what they are, why scientists introduced them, and what they do in our understandings of the nature of light.

In class we talked about the effects of cigarette smoking on birthweight. We defined a model E ( O | C = c ) = (β0)^1 + ((β1)^1 x c) where O is birthweight in ounces and C is cigarettes smoked per day. Suppose instead we used the model E(L|P =p)=(β0)^2 +((β1)^2 x p) where L is birthweight in pounds and P is packs of cigarettes smoked per day (there are 20 cigarettes in a pack). What is the relationship...

As we talked about the Software Development Lifecycle. We approached it from the standpoint of where security needs to be added to the SDLC. When code is insecure, it introduces vulnerabilities that get exploited. As security practitioners, this is where we come into the equation. However, that being said - we should be advocates for security in the development phase because it will make everyone's life easier once the software is deployed. We have to make a conscious effort to...

In this course, we have talked about four uses of empowerment and participation. We said they are part of delegation, used to overcome resistance to change, used to overcome resistance to control, and used for motivation. Now, explain why empowerment and participation work in all of these areas.
