Hunger Games Final Analysis Answers

1. In this Hunger Games lab, each student was assigned a different way to eat corks.  There was a stumpy's that had to eat food with wrists, knuckler's that had to eat food with knuckles, and pincher's who had to eat with their index finger and thumb.  The class went outside to the lower field and all stood with their backs to the center and once Mr. Orre blew the whistle, the class would turn around and try to eat as many corks as possible.  After a certain amount of time, he would tell us to stop and count of corks.  If we did not have more than a certain amount, we could not reproduce and died off.  This lab stimulated a real life situation of different kinds of animals fighting for survival.  It also demonstrated natural selection because most of the pincher's survived because they were better suited for survival.
2. The pincher's phenotype of aa was the best for survival.  The pincher's were best suited for survival because the way that they ate was the most efficient.  Instead of picking up one at a time with their wrists, pincher's could grab two at a time with far more accuracy with their fingers.
3. Throughout this lab, the population did evolve and this can be seen with the evidence that I collected.  At the beginning of the lab, the ratio of "A" alleles to "a" alleles were 0.48 to 0.52, respectively.  At the end of the lab, the ratio of "A" alleles to "a" alleles changed to 0.18 to 0.82, respectively.  The population did evolve because the ratio of the different alleles changed.
4. Some random factors in this lab were the assignment of alleles at the start, who stood where in the circle to get food, who was the child of which family, and sometimes the placement of the food.  However, some factors were not random and were done on purpose.  The factors in this lab that are done on purpose are the mating of two individuals and where Mr. Orre decided the place the food in the later generations.  If Mr. Orre decided to put all the food next to the pincher's, the whole population would turn into pincher's fairly quickly.  However, if he decided to help out the stumpy's and put the food right next to all the stumpy's, the stumpy's would have a higher chance of survival and would last a little longer in the population.
5. If the food was a different size, the population would have changed.  If the food was too big for a pincher to pinch, the pincher's would not do as well as the stumpy's because they use their wrists not delicate and precise fingers to grab things.  If the food was smaller, than the pincher's would be favored because they have precise movements and can pick up smaller items easier.
6. If there was no incomplete dominance, then the knuckler's would have not existed and the population would only be pincher's and stumpy's.  The results would have changed because the ratio of alleles would have been far more towards one species and in this case would be the pincher's.
7. Natural selection acts on the population causing the weaker traits to die out and stronger traits to be common.  Over long periods of time, the population would evolve because the population needs to adapt to their environment.
8. Since pincher's provided to be dominant, pincher's commonly got together to mate and produce another pincher baby.  However, later on in the lab, there were only a few stumpy's and knucklers.  The stumpy's bred with stumpy's, making more stumpy babies, which make the ratio of stumpy's in the population higher.  If pincher's mated with only pincher's, the whole and most of the population would be pincher's.  In nature, to ensure survival, same species mate with each other because they want their species to not die out and become extinct.
9. In evolution, a population evolves.  The population would change in order to adapt to what the environment provides.  Natural selection acts on the phenotype.  The genotype changes which causes the phenotype to change.
10. After this lab clearly demonstrated evolution and natural selection, I had a clear understanding of how these concepts work and this lab answered all my questions.
