Hardy Weinberg

Given
Population Size: 1000
q² (Homozygous Recessive Individuals Population): 0.612 or 61.2% of population

Directions:
1: Since they gave the value of q², I can find the value of the recessive allele frequency by square rooting q².
 √.612=.782 or 78.2%

2: Now that I have q, I can find p (dominant allele frequency) by subtracting the q value from 1 because p+q=1.
1 - .782=.218 or 21.8%

3: With p I can find the homozygous dominant individual population p² by squaring p.

(.218)²=.048 or 4.8%

 4: I can also find 2pq (heterozygotes) by multiplying p, q , and 2.

2(.782)(.218)=.34 or 34%

5: By multiplying p², q², and 2pq by the total population, 1,000, I can find the number of individuals of each genotype

q²- .612(1,000)=612
p²- .048(1,000)=48
2pq- .34(1,000)=340

6: By multiplying the population by 2 and the allele frequencies, p and q, I can find the number of genes of both dominant and recessive alleles.

q- 1,000(2)(.782)=1564
p- 1,000(2)(.218)=436

Answers:
q=.782
p=.218
q²=.612
p²=.048
2pq=.34
Homozygous Recessive Individuals:612
Homozygous Dominant Individuals: 48
Heterozygous Individuals: 340
Recessive Alleles: 1564
Dominant Alleles: 436

California Black Worm

After collecting data from all of the groups, I took the average of all of their results.

Diana
    A-30.7
    B-31.2
    C-26.8
Erick
   A-41.2
   B-28.6
   C-34.4
Sylvia
   A-36.9
   B-32.8
   C-42
Ivana
   A-29.4
   B-35
   C-30.2
Sarah
   A-37.2
   B-29.5
   C-35.9
Jessica
   A-12.6
   B-15
   C-17.1
Angela
   A-16.2
   B-28
   C-21.4
Claudia
   A-37.2
   B-52.8
   C-37.2
Ana
   A-37.8
   B-40.2
   C-45.6

Then I noticed that all of Jessica's averages as well as Angela's A and Claudia's B were outliers from the rest so I decided to remove them from the total average so that it will not manipulate the results.
A-35.533
B-32.883
C-34.866

In conclusion,
A- Stimulant
B- Depressant
C- Regular Water

Biology Selfies


This is my first attempt at taking a selfie. The fact that I am unskilled shines in this photo as I had trouble finding an angle that was able to show my whole face and  the tree rings at the same time. While on a group hiking trip, we stumbled upon a tree chopped in half so I brought out my phone that began an awkward 3 minutes of me positioning myself several different ways in order to get everything until I pushed the button and this is what came out. This set a theme for the most of my other selfies which became a joke within the group on the hiking trip.



When I gazed upon this small pond surrounded by green grass, I couldn't help but become fascinated as this piece of land stayed healthy while everywhere else fell victim to the California drought, turning brown and dry. The photo does not show the abundance of mini frogs that lived on this pond, proving that it was able to sustain a population.


This was a group photo taken on the hike. We began this journey eager to find something on the list and this was one of the first things we found.
