Vulcan Mating Ritual

Mating Lab: 
Purpose:  To have hypothetical offspring with at least 4 other individuals
In the class and calculate the probability of certain traits using a punnet
Square.  Next, you will perform a Vulcan mating ritual (pon farr) where
you randomly pick an allele from the other person and they randomly pick
one of your alleles.  Then observe the traits of your offspring.  Have 4 kids per mate
Keep track of the genotype of each kid.  By the end of the activity, you will have 16 kids


Method:

Write down your phenotype for the following characteristics:

Earlobe attachment or unattached   E e
Tongue rolling or not                       T  t
Cleft chin or smooth chin.                 c
Widow’s peak or not                          w
Natural curl or straight hair         n
Dimples or not       D d
Righty or Lefty       R r
Freckles or not       F f
Girl XX or boy XY

For each trait, make the genotype as alleles on two small pieces of paper.
 Write your phenotypes now:


For each mate you have draw nine punnet squares  representing
 each trait and
calculate the Probability of each trait.

Mate 1’s  genotype:_Ff WW tt nn rr dd cc  Ee__XX_________________
Punnet squares: indicate probability


choose two characteristics to demonstrate a dihybrid cross


Actual genotypes of the offspring. Draw a cartoon of your kids. Name them

osmosis lab: observing gummy candy and potato: due thursday, jan 24

Write up the OSMOSIS LAB You may hand in your lab in pairs or threes
THIS LAB IS OUT OF 60 MARKS

1.  Title of Lab:  Make up your own title of this lab     2 marks
2.  Collaborators:  Write the full names of the investigators and write down what percentage of the write up was done by them     3 marks

3.  Purpose of lab:  Write a short paragraph describing your purpose:  5 marks
4.   Materials:  Write a list of materials that you used for your experiment      5 marks
5.   Procedure:  Write a step by step procedure describing our three out of experiments:

TWO EXPERIMENTS:
PART 1: observing gummy candy in water and in a hypertonic sucrose solution
PART 2: observing potato pieces in water and in solutions of  increasing sucrose concentration

Write a step by step clear procedure that is easy to understand.  Also, make a cartoon of your procedure:  

procedure is out of 20
17-20/20    excellent, clear writing and pictures
13-16/20    very good procedure with pictures
10/20          procedure is written 
0-9/20          procedure is hard to understand

Observations and Discussion   /20

SHOW YOUR OBSERVATIONS AS PHOTOS AND DESCRIPTION. MAKE A GRAPH OF YOUR POTATO OBSERVATIONS. FOR THE DISCUSSION, EXPLAIN HOW YOU GOT THESE RESULTS AND INCLUDE SOURCES OF ERROR

17-20/20      you have a keen eye for detail in observations and you write your observations well: your pictures are very clear.  You understand why the phenomena happened and you explain it clearly. You show exceptional insight. 
13-16/20      very good write up.  You summarize your observations and your explanations are clear.  You clearly reflected on this.

0-11/20   you need to spend a bit more time describing the phenomena and also explaining it

Conclusion      out of 5
You summarize your findings in the conclusion.

Have a great Winter Break!

After a restful break, we will do a unit on Genetics and Cell Transport.  We will also spend some time on Cell respiration.

Test Questions for Friday

Help yourself to a piece of 11 by 17 paper.  Put your name on it.
ONE SIDE OF PAGE:
Answer the following questions using illustration and using the vocabulary words:

Lac Operon
structural gene
operator gene
regulator gene

cAmp
glucose
lactose
Cap
Promoter, Operator
Lac z,  Lac y,  Lac A

1.  What is the purpose of the Lac Operon? 
2.  Draw the Lac Operon, and label the regulator gene, he cap, promoter,  operator, lac z, lac y, lac A and the RNA polymerase creating the mRNA.  Draw, label and identify the three proteins encoded by lac z, y and a
3.  label the purpose of the three proteins encoded by lac z, y and a

4. Explain in an illustration how the lac repressor works
a.  to inhibit mRNA synthesis in the absence of lactose
b.   to cause mRNA synthesis to happen in the presence of lactose
c.   Include the role of cAMP in your illustration

OTHER SIDE OF PAGE:
Draw mitosis and meiosis, side by side.   Assume 2n=4      and     n=2
label and  colour code the chromatin/chromosomes/chromatids.  Explain what happens in each step.  Include the following words:   diploid, haploid, homologous pairs, centrioles, spindlefibres, interphase, prophase, metaphase, anaphase telophase
