HWEEZY Calculations

p=.35

p2=.12

q=.65

q2=.42

2pq= .455

1. Take the given value, .42 for q2, and find the square root of it. This is q.
2. Take your value for q,.65, and subtract it from 1. This is p.
3. Take your value for p, .35, and square it. This is p2
4. Plug in the p & q values into '2pq' and solve. 2(.35)(.65)= .455, this is 2pq.
5. To find the frequency of each genotype, take the value of p2 for homo dom, q2 for homo recessive, or 2pq for hetero, and multiply each individually by 1000 (the given population number). (.12 x 1000 = 120, .42 x 1000 = 420, .455 x 1000 = 455)

Black Worm Mystery

After taking a look at the data compiled in class, I believe that:


Cup A was the Normal water

Cup B was the depressant

Cup C was the stimulant


I came to this conclusion by taking all of the data from the chart, and finding the average number of pluses for each cup per group. Then, I took all of the averages for each cup and found the average of those. I ended up with three total averages, A= 33.33, B= 32.22,C=34.33. I took the lowest number and attached it to the depressant, the highest to the stimulant and the middle number to the normal water.
