period 7,8 (LAB):
 
1. Evolution basics —-> Angiosperms and pollinators = Coevolution
2. pollinate Fast Plants/marble notes on reproductive parts of a flower/seeds
*We kept the Test Cross Plants separate so that we did not contaminate our dihybrid cross.  Everyone pollinated all test groups EXCEPT the true breeders that we will use for the test cross.
 
5 people pollinated the test cross plants with the bee sticks AFTER they were done with the Dihybrid Cross pollination. These 5 people threw out their bee sticks after the test cross pollination.
 
3. Count Leaves, size of leaves, buds per flower to gather other health data to test your hypothesis.
  Most did a random sample from each group.
 
 
4Add to lab!
 
THEO has generously counted his LED test group for the entire class to add to LAB 2.
We will make another data table and graph (this one will be a bar graph).
 
We are trying to see if another the health metric (number of flowers or number of flowers per plant ) will provide the same results as our LED and fluorescent data.  We are in essence adding a test 2 as in the ant lab!
 
The idea is simple. If plants are more healthy in one light as compared to another then those that are “more” “healthy” will produce more flowers (have more FITNESS!!!) or have more leaves to utilize more of the light.

1. Review of Statistics Quiz – collection of quiz.
 
2.  Non-mendelian /Evolution Notes:
 
    a) Use X -linked recessive disorder of color blindness to demonstrate that Mendelian genetics is not upheld.
    
          – A greater percentage of males will have colorblindness than female. How can this be if the probability of being a male or female is                50% and probability of getting a mutated X chromosome is 50% from a heterozygote?   Shouldn’t the allele for color blindness  
            independently assort so that 50% of the females and 50% of the males can have color blindness?  Why is it that more males are                    colorblind? Why does sex makes difference in this disorder?
 
            The gene for color blindness is on the human chromosome that also has the genes for female            characteristics!!!
 
        These 2 alleles (female characteristics) and color blindness are linked.  That is they are      
        located  on the same chromosome and thus cannot independently assort.  This means that 
        the female characteristics and colorblindness traits travel together in heredity!
 
        This is non-Mendelian! 
 

Because the gene is linked (the allele for colorblindness is on the same chromosome as the female characteristics trait) males cannot be carriers and cannot be heterozygotes!!!  It just takes one X mutated chromosome to have the disorder.  

 
Because of this the ratios we would expect from our cross above would be STATISTICALLY Significant  from actual results. We would expect equal number of males and female to have the disorder but that is NOT the case.  This is Non-Mendelian.
 

   If males could be heterozygotes for Colorblindness
we would expect 1/4 of all offspring AND EQUAL number of males and females having the condition.

 

1/2   x  1/4 = 1/8   probability of being a male and being                                                                                                                        colorblind.

 

The above probability problem uses the multiplication rule because the each event (separating of a different chromosome independently) is separate if you assume that the 2 traits are on different chromosomes.  This is Mendelian!!!  We would get 1 : 8 ratios!!!
 

  But males are cannot be heterozygotes for colorblindness. and thus the actual probability of being a male and having the condition is equal to :

  1/4 = the probability of being colorblind

Because the the actual ratio is 1 : 4 the 2 traits do not travel independently as Mendel always suggested.  We would use the addition rule here and count how many of the offspring would have the phenotype.  OUT OF THE 4 CHOICES IN THE PUNNET SQUARE THERE IS ONLY ONE!
 
1/4 + 0 = 1/4 of all offspring are colorblind but 50% of the males are also!
 
Evolution Basics:

Also Individuals do not evolve!!  Populations due by shifting the “normal distribution” toward individuals that have the greatest reproductive fitness = THEY LIVE LONG ENOUGH TO REPRODUCE MORE and pass on their alleles to the next generation.  This increased reproductive fitness is due to the SELECTIVE PRESSURE that the CHANGE provides!

 
IF there is not already an allele present THAT WILL HELP in the NEW ENVIRONMENTAL Conditions (Change) THERE WILL BE No EVOLUTION. This means that if an allele is not already present in low frequency BEFORE the change THERE WILL BE NO SELECTIVE PRESSURE for any allele and the population will suffer and eventually become extinct.
 
NOTICE that SEXUAL REPRODUCTION increases Genetic Diversity so much more than ASEXUAL REPRODUCTION does and thus produces more various alleles.  This variety of alleles creates the ABILITY for species to have a better chance to Evolve or survive NEW Changes in the environment.  How many current advanced species are alive today that undergo asexual reproduction?  Not many why?  Could we as humans evolved into the extremely complicated life form we are now if we did not sexual reproduce?
Asexual Reproducers ONLY get get variety when a mutation occurs while sexual reproduction Amplifies the diversity (from a mutation) by segregating chromosomes randomly, crossover, and random fertilization. 
 
ALL Evolution however starts with a mutation or a Random change of code in our DNA that creates new proteins that can stop current chemical reactions (recessive) OR START NEW REACTIONS (that make new alleles!!!)

Extra Thoughts and Maybe totally Unnecessary.
 
OK there are 2 ways to figure out the problem to figure out the probability of having 6 girls out of 10 children.
 
There is the long hand method that I did for 3 boys out of 5 kids but I stopped doing it for 6 out of 10 because I would need 1024 possibilities and I do not think I could keep going!
 
For 3 girls out of 5 children example:
Notice the total combination will be (1/2)5 = out of 32 combination. ALL girls = 1/32 and All boys = 1/32 but 3 out of 5 was 10 of 32 or 10/32 = .31 or 31 % probability when I physically counted all of the possibilities by doing it long hand.
 
Now I found a better mathematical way from looking at my old statistic book:
 
Not easy to explain but here it goes:
We know that the denominator is based on our multiplication rule (1/2 x 1/2 x 1/2 x 1/2 x 1/2) = 1/25 = 1/32
The numerator is a little challenging to explain but lets go!
WE have 3 Girls that could be placed in each of the 5 positions or age order of the children. Lets envision the 5 positions below :
     1. _____ 2:_____ 3: ______ 4: _____ 5: _____
WE can place the 1st Girl in any of the 5 positions so there is 5 possibilities.      ( 5 x           )
IF we try to place the Second Girl in the order there are 4 less possibilities
because there is already one position taken by the 1st Girl                                                 ( 5 x 4 x     )
1. _____ 2:_1st Girl_ 3: ______ 4: _____ 5: _____
The Third Girl would then have only three positions available because of
the placement of the 1st Girl and the 2nd Girl so we complete the formula:                  ( 5 x 4 x 3  )
1. _____ 2:_1st Girl3: ______ 4: 2nd Girl  5: _____
So we get (5 x 4 x 3 ) = 60 BUT thus value gives me all the combinations of the THREE Girls INCLUDING combinations that we would count as the same.  For instance these three combination
of Girls are in the same position but are treated differently because we are labeling them 1st Girl, 2nd Girl, and 3rd Girl. 
 
1. _____ 2:_1st Girl3: ______ 4: 2nd Girl  5: 3rd Girl
1. _____ 2:_2nd Girl  3: ______ 4: 1st Girl   5: 3rd Girl
1. _____ 2:_3rd Girl  3: ______ 4: 1st Girl    5: 2nd Girl
 
Because we do not care about OUR labeling of the Girls as they are all girls we need to lower our 60 combination value by the following:
There are 3 Girls and they fit in each in each position (3) equally so the 1st Girl has 3 positions to fill and the second Girl would have 2 positions left and thus the 3rd would have only 1 to give us:
                                                                                            3 x 2 x 1 = 6  
 
We take our 60 and divide by 6 = 60 /6 = 10 possibilities OUT of the 32 = 10 /32 or 5/16 = .315 probability
So for 3 out of 5 Girls:             5 x 4 x 3    =   60    =      10  /   1/2 =  10  /  32   =  .315
                                                      3 x 2 x 1         6
 
S0 for 6 girls out of 10 the math looks this way:
 
                             10 x 9 x 8 x 7 x 6 x 5 =   151200  =   210  /  1/210 = 210 / 1024 = .205
                               6 x 5 x 4 x 3 x 2 x 1           720
 
 
HERE IS MY WORK:  I DID THE LONGHAND WORK FOR 3 OUT OF 5 GIRLS FIRST.
 
End of Week 4!
