Test Day

So we got off to a late start (I needed the extra sleep) but everything is running smoothly now.

Test was taken today I hope all did as well as they should have.

Everyone have a Merry Christmas and be ready to work when we get back!

Dissappointing Day!

So I made a deal with all of my classes yesterday. I told them that everyone in the class would simply complete their test review I would read the test to them today so they would have an easier time. An early Christmas present if you will. But low and behold after being given 55 minutes in class and an entire evening NO class even came close to fulfilling their end of the deal.

So today we went methodically thru the test review. There is not one single thing on the test that wasnt reviewed today. If they will take the time to actually study tonight they should do quite well!!

Heres to hoping they do!

Test Review

Well we are in the home stretch for 2007. Today we began the test review. It will be posted below. Please complete this it is FREE points!!!! Tomorrow we will continue to review and finish the week with a test on Friday!

CHAPTER 8
TEST REVIEW SHEET
1) Explain the difference between homozygous and heterozygous.
2) List and describe Mendel's three laws.
3) Who was Gregor Mendel and why was he important?
4) Explain the difference between P, F1, and F2 generations.
5) Know all the key words from Chapter 8.
6) What is the difference between dominant and recessive traits?
7) What is the difference between genotypes and phenotypes?
8) What is probability?
9) How is a monohybrid cross different from a dihybrid cross?
10) What is a test cross?
11) Explain the difference between codominance and incomplete dominance?
12) Cross RR and rr. Give the genotypic ratios for the F2 generation.
13) What are the possible phenotypes for the following cross? Tt x tt. T=Tall t=Short
14) What would be the possible genotypes for the cross of a homozygous Tall
green plant with a heterozygous short yellow plant?
15) Give the phenotypes for the F1 produced by the cross of a homozygous tall
round plant with a homozygous short rough plant where tall and rough are
dominant.

Lab Day

Yesterday we finished with Punnett square problems. Now all of you should be able to sucessfully complete monohybrid and dihybrid crosses.

Today we made babies in class. No not really but we did a lab that showed how probability comes in to play when talking about traits being passed down from parents to children. The kids used coin flips to determine what the offspring looked like and then they had to draw the baby! Lets just hope their real kids in a few years look better than their drawn babies lol!


Tomorrow we begin the test review. Thursday will be the final test review and Friday Merry Christamas we have our last test of the year!! (2007 that is)

Friday at last

So here we are on Friday. We have spent the last three days working on Punnett Square problems. We started with one trait problems and should now be able to work three trait problems. Remember 3 traits 8 possible gametes and 64 squares in your Punnett Square.

Next week will be more Punnet square problems, a lab, a test review and a test next Friday.

If I were you I would not miss next week because trying to retain this material over break is not a good thing to try when your grade depends on it!! Speaking of break I hope everyone enjoys their time off but when we get back we have to hit the ground running! There will be no EASING back in, the SOL test is just around the corner!

8 more days!!!

Today we begin the last lecture of the year!!! Yes thats right 2007 is dwindling. We have 8 more days left well really 7.5 because this Friday is screwy since we have the student faculty basketball game. We have lots to get thru before the test next Friday the 21st!

If I were you I wouldnt miss any of the days from here until break because they are going to be jam packed and I would hate for you to get behind starting the new year!!!

Long Weekend

Well I hope all of you enjoyed the unexpected long weekend due to the dangerous ice that lasted a couple of hours. Well now it is time to get back to business.

Today we will be beginning Genetics. I really hope we can get thru this by next Friday but we will just have to see.

The over view is posted below . Please complete this ASAP!!!


Chapter 8 Overview


Key Terms :
Trait Genotype
Gene Phenotype
Hybrid Homozygous
Pure-Bred Heterozygous
Dominant Trait Probability
Recessive Trait Punnett Square
Allele Incomplete Dominance
Polygenic Traits Codominance





Questions:

1) Why is Gregor Mendel important to the field of Genetics?



2) What is genetics?



3) Describe Mendel’s three laws.



4) What is the difference between a monohybrid cross and a dihybrid cross?




5) What is the difference between homozygous and heterozygous?

Test Day

So here it is Thursday and we took a test on Mitosis and Meiosis.

This week we have taken a quiz, done a lab, a test review and now taken a test. Some of my classes are really starting to get it and are putting the effort into being sucessful some are are not.

Tomorrow is a lousy day, we have the student faculty basketball game which means crazy schedule and wild kids!!! But we will charge forward and start on Chapter 8 Overview (another free points assignment)
