2018 HS Bio Cary

Hi folks, The camera was doing strange things so this is the video from my Chapel Hill class.  Same material just different classroom. https://youtu.be/bKkmbvMAFAQ Best, Jim Mueller (919) 907-3217

Hi folks, Today we took the time to dive a bit deeper into evolution and discuss genetic drift and the Hardy-Weinberg principle. For homework, please write at least a paragraph essay on your thoughts as to whether or not humans are evolving.  Tell me your evidence for your argument.  Some thoughts on things to include in your essay: Darwin's postulates, Harvey-Weinburg, adaptations, survival of the fittest.  Something to keep in mind for this is that evolution is a change over time.  It is not necessarily a positive or negative change, just an overall change in the gene pool over time. Also please do the following questions that relate to the lab we did this week. 1. What did the poker chips represent?  Why did we use two different colors of chips? 2. What was the original gene frequency of the F and the f alleles before selection occurred?  3. How did the gene frequency of the F and f alleles change by the 10th generation (or at least as far as you got)?...

Hi folks, What I was planning on using the laptop for will work better next week.  If you can bring one next week (I'll send a reminder) that would be great. See you all soon! Best, Jim Mueller (919) 907-3217

Hi folks, If you can, please bring in a laptop to class tomorrow.  We are going to be running a computer simulation for part of class tomorrow and if a few folks bring in laptops we can do it in groups. Thanks! Best, Jim Mueller (919) 907-3217

Hi folks, Today we dove a bit deeper into the concept of evolution. We took a look at how the theory came about and how the theory works. For homework this week please read pages 277 - 290. We are not going to spend much time on this in class but it's fascinating material on how life may have come to be on Earth. Also finish chapter 15 by reading pages 308 - 310. Do Question 2 and questions 4 - 16 on page 312.

Hi folks, Today we spent some time breaking rules. Mendelian genetics rules that is. We learned about a few of the exceptions to the basic heredity through dominant and recessive genes. We also began our next block on evolution. Read pages 302-306 and do questions 1-8 on page 307. Also, make your own quiz. Create questions based on the following concepts and then solve the questions. I'll give you 3 points of extra credit if I end up using your question on an upcoming quiz. Have fun! 1. Typical Mendelian genetics problem that can be solved using a monohybrid cross. 2. Typical Mendelian genetics problem that can be solved using a dihybrid cross. 3. Incomplete dominance problem that can be solved using a monohybrid cross. 4. Codominance problem that can be solved using a monohybrid cross. 5. A blood type problem problem that can be solved using a monohybrid cross.

Hi folks, Just to be clear, do not do the entire Dragon Genetics worksheet that we did in class.  Just do the worksheet I created with the 20 questions on it. Best, Jim Mueller (919) 907-3217

Hi folks, Today we took the time to really try to understand what is going on with those punnett squares.  What are they representing and what are we really trying to see with them.  To do that we did an activity called Dragon Genetics which simulated the process of independent assortment in meiosis to create gametes.   Since we did this in groups in class, I want you to take a bit more individual time with the activity.  I'm including the write-up for you to refer to and I'm also including a worksheet.  Please do all the questions on the worksheet.  When you are done, take a look at the answer sheet to check your answers.

Hi folks, Happy 2019!! Apparently I never sent the homework email after class last week.  Sorry about that everyone! We are now at the point where we can see how genetic material from two parents intertwine to create an new and unique individual. This is the beginning of genetics. We did a lab where we did a survey of students to see what traits have been inherited.  We also introduced the concept of Punnett squares. Read chapter 9 pages 173 - 186 Do questions 1 - 14  and 16, 17  on page 188 Also  Do the enclosed worksheet.
