It's Snowmageddon! A Blizzaster!, The Snowpolalypse!

Hey everyone! Hope you are enjoying your day off! If you are reading this, post something about your snow day!  Maybe a picture of the snow?  So, just a friendly reminder that it would be WONDERFUL if you keep on track with the homework on moodle.. you will not be penalized if you don't, however, your weekend will be bogged down with homework if you don't!  Why am I asking you to do this?

1.  The test is STILL planned for next week (last I hear, still Weds.... but now that tomorrow is cancelled to, not sure if that will be)
2.  The test will STILL cover the same information
3.  You're gonna have to do it anyway!
4.  You'll have less to do over the weekend!

That is my CAR behind Max!!!

Be safe everyone!  See you soon!

HAPPY NEW YEAR!

Hope everyone had a wonderful and restful Winter Break!  The next two weeks is going to FLY by... finals will be here before you know it!  To help get yourself ready for finals, get your materials from your classes organized SOONER than LATER.  Figure out what material is the hardest for you and start there... so you have time to review that material more than once before the exam.  We are going to do one more short unit before finals... we will learn about reproduction and hormones. 

Happy and Healthy 2011

Genetic Disorders and Karyotypes

In class today, we started off by getting two cookie monster stamps for the pedigree and genetic disorder problems.  We discussed how to analyze a pedigree chart to look at the inheritance of traits in families.  Remember, you need to look at the parents and the children of a given individual to try and determine the genotypes.  You cannot always determine the genotype with the information given.  For example, Question #3 on page 49... you cannot determine the genotypes of individuals E I J M N.

We then looked at a few images of karyotypes and talk about how to match chromosomes and analyze karyotypes.  Below is an image of a karyotype... do you know what genetic disorder this person has???

That's right!  Kleinfelters Syndrome!

Below are a few good links to practice analyzing Karyotypes.

Connection between Meiosis and Mendalian Genetics

One of your classmates asked "what is the connection between meiosis and what we are doing now (ie: punnett square problems)... below is what I wrote as I explained the answer. Can you follow it?

Multiple Alleles

I hope you enjoy this one! it took me FOREVER to get it...i kept screwing up! Also, be sure to look at my post from last night!!!

Crazy News!!!!

Have you heard? Scientists are redefining what it means to be living? Do you know how? Have you heard about the new biological discovery that was announced on Dec 2nd???? If so, email me... be sure to completely explain (in your own words!) what the discovery was, the science (and genetics) behind the discovery, and WHY its sooooo very cool!!!

Dihybrid Crosses

In Case You Didn't Get it....

Meiosis.. NOT Mitosis!

Welcome back gang!  Today was a first day back after a LONG Thanksgiving break.  Everyone was thrilled to be back at school... I know I was! 

Today we started talking about meiosis.  First of all, meiosis is NOT mitosis... they are quite different processes... though they make look similar the outcomes are very different. Mitosis is normal cell reproduction.  Meiosis, however, is the process that makes egg and sperm.

We spent a lot of time talking about chromosome numbers and the difference between haploid and diploid cells.  It is very important that you understand that diploid cells have HOMOLOGOUS pairs of chromosomes... in other words, two copies of each chromosome....  Homologous chromosomes contain the same genes in the same location on the chomosome, however, they may be different FORMS of the gene.... that is because one copy came from your mom and one came from your dad.

If you are confused about what happened in class today, it is ESSENTIAL for you to get it squared away ASAP because the coming stuff will confuse you more if you don't have a solid foundation. 

Below are the notes from today's class if you missed it!

This always makes me laugh! Anyone wanna learn it an sing it for the class???






A good summary of meiosis...but there are others out there on youtube... find 'em! Post 'em!

Homework for tonight...
-UP 13-14 - be sure to color and annotate (ie: notes in the margins)
-READ 11.4... do either a flow map titled "Steps of Meiosis" or a double bubble map titled "Meiosis vs. Mitosis"

John Snow and Cholera

Since I am such a John Snow fan...i found these videos that i thought you might exjoy.  Watch them and email me the answers to the following 2 questions..
1.  Who was often spared from cholera outbreaks and WHY?
2.  What was the name of the other 'protagonist' in Stephen Johnson's book Ghost Map?

Video Thoughts?

Did anyone have any thoughts about Friday's film?  I have seen that film many times now, and everytime I watch it I always really admire those 'disease warriors' who worked so tirelessly to bring vaccines to remote parts of the world.  I feel that so many people are only concerned with themselves... to travel to places like India and Africa to try and rid the world of such horrible diseases really says something about those volunteers..  They really made a difference in the world... not everyone can say they have done so.  How amazing would it be to be able to rid the world of HIV like they did with smallpox? What were your thoughts?  Reply to my post with a comment as to what your thoughts or reflections were on the movie.
