Questions 1. What is the gene pool of this population? The Gene pool is Y,Y Y,y y,y 2. What is the gene frequency? The gene frequency is 3:3 Experiment 1: Questions 1. What is the gene pool of beaker #1? 26 red, 24 blue 2. What is the gene pool of beaker #2? 24 yellow, 26 green 3. What is the gene frequency of beaker #1? 1:0.92 4. What is the gene frequency of beaker #2? 1:0.92 5. What can you say about the genetic variation between these populations? That the genetic variation between these populations, are almost a complete 1:1 variation. Experiment 2: Questions 1. What observations can you make regarding the gene pool and gene frequency of the surviving individuals? That when you…show more content…
Why or why not? Yes. I thought beaker 2 wouldn’t of been close to even since I had to remove randoms beads for beaker 3. It just flipped what I thought would of happened. 3. What observations can you make about the genetic variation between the parent and founding populations? That even if there is a 75% chance of a bead or allele being in the mix it is not always true that you will get it. Experiment 4: Questions 1. How many total base pairs are in all the mammalian genes? 3,000,000,000 base pairs 2. What proportion (%) of the total genome does this represent? 100% 3. What is the probability that a random mutation will occur in any given gene? A mutation can occour at anytime for no reason at all or by outside influences. 4. Only 1 out of 3 mutations that occur in a gene result in a change to the protein structure. What is the probability that a random mutation will change the structure of a protein? 33% Experiment 5: Natural selection Experiment 5: Questions 1. Do you observe a selective advantage or disadvantage for the red or blue beads on the blue habitat? Why? Disadvantage for red and advantage for blue 2. How did the distribution of phenotypes change over time? Became more red. 3. What results would you predict if starting with the following population sizes? 1000 180 red 60 blue 100 18 red 6 blue 10 1:1 Experiment 6: Questions 1. What is the remaining ratio of alleles? 3 SS 5
