Today’s Lesson – well it as last year – we will use data that I will post above but the concepts are the same.
11/2 – Tuesday’s Homework: –
1. Please read the article about Stanley Miller below:
Be prepared to to have a RAT Quiz on this article tomorrow.
I will explain the Rat Quiz tomorrow.
Would you rather have a form tonight??
It might help to make a NORT of the article.
11/3 – Wednesday – B Day –
| purple green: 173
purple yellow: 52
non-purple green: 98
non-purple yellow: 23
| = 346 total individuals
= 52 + 23 = 75 individuals that are homozygous recessive
| Yellow baby leaf
|q2 = 75/ 346||q2= .22||√q2= √.22
q = .47
p = .53
1 – .47
|q = .47|
|Using the AlleleA1 simulation, Genetic Drift of allele A1 (p) or the dominant allele LEAD to the “death of A1 alelle” after 300 generations of 346 individuals. This is due to random events in producing gametes in meiosis AND in Random fertilization.
This what is meant by the drift! With no other forces working, No Natural Selection, Gene Flow, or inbreeding an allele is lost from the population. Remember we are tracking only 1 allele and that is very possible that this happening at other alleles in the genome of the species.
Genetic diversity is decreasing and this population is becoming less like the populuation it once belonged to.
11/3 – Wednesday’s Homework: –
1) Read article on the RNA world Hypothesis : http://www.ncbi.nlm.nih.gov/books/NBK26876/

End of Wednesday..
11/4 – Thursday – A Day –
The Origin of living systems is explained by natural processes.
The process of evolution explains the diversity and unity of life. A number of experimental investigations have provided evidence that the conditions early in the Earth’s history provided an environment capable of generating complex organic molecules and simple cell-like structures. For example, in the “organic soup” model, the hypothesized primitive atmosphere contained inorganic precursors from which organic molecules could have been synthesized through natural chemical reactions catalyzed by the input of energy. In turn, these molecules served as monomers (building blocks) for the formation of more complex molecules, including amino acids and nucleotides. Some models suggest that primitive life developed on biogenic surfaces, such as clay, that served as templates and catalysts for assembly of macromolecules. Under laboratory conditions, complex polymers and self-replicating molecules can spontaneously assemble. It remains an open question whether the first genetic and self-replicating material was DNA or RNA.
11/4 – Thursday’s Homework: –
*Today’s best out of 2 RAT quiz will become extra credit on the next test.
If your best grade out of the 2 was an 80 then take the 80 / 10 = 8 / 2 = 4 points on the next test.
1: Please begin your write-up of the Brine Shrimp Lab. It is a EVOLUTION LAB!!!!!!!! I will share with you a link to work on the lab. WE have already gathered data and made a table and a graph with error bars. You should complete the Background, Question, Hypothesis, materials, Procedure tonight.
Please use all the concepts that we learned from Evolution into this lab.
The lab is due Monday 11/8 and the format of the formal write-up is as follows:

| Based on 5 conditions: No mutations, large population size, no gene flow, random mating, and no natural selection, the frequency of allelles for a train will stay constant. The equation:
(p + q) = 1 (For total alleles in population)
p2 + 2pq + q2 = 1 ( For the individuals)
