1. In this lab we were all assigned a species of bird, either a stumpy, knuckler, or a pincher. Stumpies were at a disadvantage because they picked up their food with their wrists, knucklers with there knuckles, and pincher with their thumb and index fingers. Once we has been assigned a species, we waited until the food was put out by our teacher, and then we gathered as much as we could to survive. This simulated how species have to survive in the wild, with a limited food source and lots of competition to survive and reproduce.
2. The phenotype that was the best at capturing food was the pinchers. This was because they only had to grab between their two fingers and not something drastic or hard such as grabbing between wrists like a stumpy. Pinching is a normal human, easy, and basic human movement and the rest were not.
3. The population evolved so that the recessive allele ended with the most members in it. I know this by looking at my data. In the very start of the experiment, the polulation was closed to balance with the A allele frequency being .52 and the a allele frequency being .48. By the end of the experiment, the A allele frequency was at a mere .27 and the a allele frequency was at .73.
4. In this lab, one of the things that was not random was the mating. People mated with others that they thought would give them better offspring, for an example a pincher would most likely always mate with a pincher. Something that was random in this experiment was the food placement. The food was placed in random places by our teacher, so that we had no idea where it was. If the food happened to be near you, you were lucky and if it wasn't you were out of luck and not guaranteed to survive through that round.
5. If the food had been smaller, I think it would have made it even harder for the stumpies to survive, because it would have been very hard to grab such a small object with your wrist. However if the objects were larger, it would have made it harder for the knucklers because large objects are harder to fit in between your knuckles, as it is not a large space. Since the pinchers are such an adaptable species I don't think having larger or smaller food would have affected them that much, because you can grab almost anything with your fingers.
6. If there was not incomplete dominance, the results may have been different. This is because the knucklers would not be in the population and so there would be less competition overall. There would just be competition between the stumpies and the pinchers.
7. Natural selection selects certain genes that are advantageous for survival, which leads to evolution. This is because as they pick the traits that are better suited to survive, the other traits are weeded out, and the population starts to evolve such that the population now looks like the survivors.
8. Some strategies that individuals adopted to survive were laying on top of the food to claim it, and then taking it all for themselves. This ensured that they got a good amount of food, because no one else could touch the food that they were laying on top of. This would effect the allele frequency, because the frequency of the individuals species with better strategies would go up. This relates to nature because in nature animals adopt certain traits that can help them survive and reproduce such as camouflage.
9. In evolution the species with the stronger traits for survival evolves. Natural selection acts on the phenotype because nature doesn't know your genotype, but it does know your phenotype. So the species that are better suited for survival will continue to reproduce; survival of the fittest.
10. I think this lab was very beneficial to my understanding of this topic, and I do not have any further questions remaining.
