1/27 Biology Recording - Non-Mendelian Genetics

Part 1

Part 2

1/27 Biology Update and homework due 2/3

Hi folks,

Today we spent some time breaking rules. Mendelian genetics rules that is. We learned about alternatives to Mendel's simple recessive/dominant genetics as we learned about co-dominance, incomplete dominance and multiple alleles.  

For homework this week:

First, take a look at this website https://hobart.k12.in.us/jkousen/Biology/inccodom.htm.

Do the sample questions at the end of each section (there are 5 in all).  Check your answers as well.

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. Be creative and 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.

1/20 Recording - Dragon Genetics and dihybrid crosses

Part 1

Part 2

1/20 Biology update and homework due 1/27

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 full write-up for you to refer to and I'm also including a worksheet.  Please do all 22 questions on the worksheet (don't do the questions on the write-up for the activity).  When you are done, take a look at the answer sheet to check your answers.  Be sure you get those punnetts correct!

There will be a quiz next week so be sure you study the lesson/homework on asexual vs. sexual reproduction, monohybrid crosses and dihybrid crosses.  Stay sharp on meiosis and mitosis and everything that entails as well.

Fwd: 1/14 Biology update and homework due 1/21

Hi folks,

We are now at the point where we can see how genetic material from two parents intertwine to create a 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.

For homework this week:

Read chapter 9 pages 173 - 186

Also 

Do the enclosed worksheet. 

Be sure you master that meiosis and your punnett's. Sure looks like quiz material to me.  :)

Answer Sheet for Biology Homework

Hi folks,

For some reason the original sheet didn't convert to a .pdf.  Here's a .pdf version.

1/6 Biology Recording - Asexual vs. Sexual Reproduction and genetics vocab

Part 1

Part 2

1/6 Biology update and homework due 1/13

Hi folks,

Today we began preparing for our unit on genetics.  We learned about sexual vs. asexual reproduction and the advantages and disadvantages of each.  We also learned a bit of the vocabulary needed for next week's genetics lesson.

Two assignments for homework this week.

1.  Do the questions in this email.

2.  Do page 1 of the enclosed .pdf.  (you did page 3 last week but you may want to do it again to review.  It makes great quiz material.  :)  )  By the way, in question one I'm looking for putting the stages in ORDER from 1 - 9.  This is pretty tricky so take your time on this.

Answers are included a separate .pdf. 

1.  What are the five types of asexual reproduction?  (This website has a nice write up of each if you want to take a look. https://www.thoughtco.com/types-of-asexual-reproduction-1224623)

2.  Now that you've given me a list of all five, please tell me what each one is.

3.  Please list 2 advantages for sexual reproduction.

4. Please list 2 advantages for asexual reproduction.

5.  Please list 2 disadvantages for sexual reproduction.

6. Please list a disadvantage for asexual reproduction.

7.  In humans there are 23 pairs of chromosomes but there are really 46 chromosomes.  Why do we say that there are 23 pairs instead of just saying 46 all the time?  It's not like we say there are 6 pairs of eggs in a carton or 3 pairs of Coke in a six pack.

8. Cousin Ted walks up to you and says,  "Why do they say homologous chromosomes and not identical chromosomes.  Aren't they identical? What's with the fancy words?!  Jeesh!"  How do you respond?

9.  Starting from just before the s phase and finishing at the end of meiosis, fill in the blanks to tell me how we go from 46 chromosomes to 92 chromatids to 46 chromatids to 23 chromatids.

In S phase the chromosomes duplicate and go from ______  to ________ chromosomes.

In prophase 1 the chromosomes concentrate/condense to form ____________________.

After Telophase 1 we end up with ___________cells, each of which has ____________ chromatids.

After Telophase 2 we end up with _______cells, each of which has ___________ chromatids.

10.   What is the definition of allele?  

11.   Cousin Ted is back "Hey, alleles and genes.  Same things!  What's the difference?!"  Explain gently to Cousin Ted what the difference is and give him two examples.
