Hweezy Problem

• q² ( Frequency of Homozygous Recessive Individuals)= .05
• p² ( Frequency of Homozygous Dominant Individuals)= .61
• 2pq ( Frequency of Heterozygous Individuals) = .34
• q ( Frequency of Dominant allele)= .22
• p ( Frequency of Recessive allele)= .78
• Number of Homozygous Recessive Individuals in population= 50
• Number of Homozygous Dominant Individuals in population= 610
• Number of Heterozygous Individuals in population= 340

Steps

1. Square root q² to obtain q
2. Subtract q  from 1 to obtain p
3. Square p to obtain p² 
4. Multiply p, q, and 2 to obtain 2pq
5. Multiply q² , 2pq, and p²  to 1000 ( the population) to obtain the number of individuals of each genotype.

Solutions in Worm Lab

Worm Lab Solutions

 In the worm lab, Solution A is the depressant, Solution B is the stimulant, and Solution C is the normal solution. When the 

numbers in each group were averaged, Solution A had the lowest pulse rates. Solution B had the highest pulse rates, and Solution C had the medium pulse rates. To come to this conclusion I averaged the numbers for each group, day, and solution separately. I then looked down at each day for each group and listed the solutions from slowest to fastest. When finished I tallied up the number of times each solution appeared in the 3 categories, slow, medium, and fast. A ended up the majority in slow with 7 appearances, B the majority in fast with 6 appearances, and C the majority in medium with 6 appearances. With this I came up with the to the conclusion that A is the depressant B is the stimulant and C is the normal solution.

 Ecology Selfies

     The Ecology scavenger hunt was a tremendously enjoyable experience. It was tiring, frustrating at times, and sometimes difficult but overall it was fun. The teamwork aspect of looking for things with friends and the occasional competition for items on the list enriched the whole "scavenger hunt." The frustration was present though, especially with living things. However the difficulties just made everything more rewarding when something was accomplished. Speaking of what was accomplished here are three of my favorite ecology selfies.

This group selfie is one of my favorites because it shows off the group of friends I went hiking with for the collection of selfies. It really demonstrates the teamwork aspect of it as we put six minds  together to accomplish a goal. Not only did working in a group improve our work but it also made the experience more enjoyable. Another reason I like this selfie is my face in the selfie just makes me laugh every time.

This picture is also one of my favorites because it shows off our creativity. One of the words we struggled to find a way to photograph was parasitism. Our group was confused and it was sort of just put off. However I had a light bulb moment and thought, " Hey we can probably act it out, she did say be creative." The product of this thought was the picture.

This last selfie showcases what I said before about the difficulty of some pictures making them more rewarding when accomplished. Throughout the hiking trip I've tried, and failed, to take a selfie with a bird numerous times. It was frustrating and I went home that day without that selfie accomplished. Now as fate would have it, weeks later walking around U.C Berkeley, I would have the perfect opportunity to get a selfie with a bird. When I finally took it, the satisfaction I felt could not be described.

    So to summarize the Ecology Selfies were a mix of fun times with friends, frustration, fatigue, and an unrivaled sense of accomplishment.
