Hunger Games Final Analysis

  1. In this Hunger Games Lab, we ate corks using different methods including wrist, thumb/index finger, and middle finger/index finger knuckles. Those with less food died off. Those who survived mated and tossed coins to simulate sex. The offspring was given the traits. As each generation progressed, the allele frequency changed. This stimulated natural selection and a real world population of organisms trying to survive.
  2. The phenotype that was the best at capturing food was the pincher phenotype. This was because the pinchers could get the corks the easiest because using your fingers is easier than using your knuckles and wrists.  
  3. Our population did evolve, according to the defintition of evolution. This is because our allele frequency changed over time. The allele frequency changed from 52-48 to 31-69 to 42-58 to 39-61 to 32-68 to 27-73 40-60 from the ration A-a. This change meant that the genotype aa was more favorable, leading more of us to try and get this genotype.
  4. The non-random was the equal allele frequency at the beginning. This would help us understand the drastic change more. The non-random part were the people who retained the phenotypes. For example, if a person with big jackets and big pockets were to particiapte in this lab, he/she would do better than most, no matter their phenotype. In addition, the food was scattered randomly. Some people were farther away, and some were very close. Lastly, the physical attributes of the participants also affected the outcome. Those who are larger can scoop the food and get the food in large volumes. Those who are faster can get to the jackpot or the big pile in the middle faster.
  5. If the food were larger, then the pinchers would have a more difficult time, but the stumpies would actually thrive. However, the knucklers would die first If the food were smaller, then the stumpies would die off quite fast, but the pinchers would still thrive. The knucklers would have some difficulty, but would still survive. This may be found in nature if humans intervene with nature. Some small fish in the ocean may die becuase of toxic waters, whilst big fish survive.
  6. If there were no incomplete dominance, then knucklers would not exist. However, the stumpys would be much more dominant, with the allele frequency being more drastic. 
  7. Natural selection is the catalyst and the driving force behind evolution. Those with favorable traits are naturally selected, and the next generation begins to look like the winners.
  8. Some strategies that individuals took were to mate with those with better phenotypes or those with the same phenotype. This made it so that most offspring were pinchers and knucklers. This was natural selection, becuase those with unfavorable traits cannot mate. You cannot mate if you are dead. 
  9. In evolution, an individual does not evolve. Instead, the general population evolves. Natural selection acts upon both phenotype and the genotype. The new generation's genotype consists of the dominant allele and the majority of phenotypes is the dominante phenotype. In this case, it would be the pinchers,
  10. My only question is if this stimulation continued for many trials, will the allele frequency ever reach a limit?
