2. Knucklers because they passed their genes better. The chances of getting a knuckler from mating was 50%, the chance of getting a pincher was 25% and the chance of getting a stumpy was 25%.
3. My hypothesis was if species survive in an environment over time, then evolution will occur. My hypothesis was correct. According to graphs we made, the "a" allele was more frequent than the the "A" allele. After the first trial, the frequency for "a" were more frequent than the "A" allele. This happened because more pinchers(aa) were produced than stumpys(AA). For example, In the second trial the frequency for the "A" allele was 37% and the frequency for the "a" allele was 63% in the third trial, the frequency of the "A" allele was 19% and the frequency for the "a" allele was 81%. Population evolved over time because of the amount of stumpys, knucklers, and pinchers were different for every trial. More knucklers produced over time than the pinchers and the stumpys. Natural selection had caused species to change over time by evolution. This was caused when the knucklers survived better in the environment than the stumpys and pinchers and more knucklers were produced than the other two phenotypes.
4. The things that were random was the sizes of people's pockets. People with bigger pockets could pick up more food and the people with small or no pockets could not pick up as much food as they could which resulted into evolution of populations that had bigger pockets than other and could survive better in the environment. Another thing that was random in the lab was where the food was placed during rounds. Most of the time, food was placed around the area, but sometimes, the food was placed in one spot or in a few spots which made it easier for people who were near the area with a lot of food get food easily and the ones that get more food survive and produce more offspring better than others. Another thing that was random in the lab was the places people were. Every round, people were in different places around the area and when every round would start, the people who were near the food got more of an advantage to get more food. The things that were nonrandom was the mate choice and trait. At the end of each round, we would pair up with other species with same or different genotypes and flip a coin to figure out what the offspring would be by determining the genotypes and its trait. This affects evolution by how mate choice always occurs in evolution.
5. Yes, if the food amount was larger in an environment, more species with certain traits would survive better in the environment and more offspring will be made and if there was less food in an environment, less species with certain traits would survive and less offspring will be made.
6. Yes, there would be a different amount of species with certain phenotypes every round and the allele frequency would change.
7. The relationship between natural selection and evolution is that they both contribute to population change.
8. People competed with others for food, found spots with food with no one around them, pushing and shoving other people around for food and pick up more food at once This would affect the allele frequency by increasing the frequency for each allele.
9. In evolution, the species and allele frequency change and natural selection acts on unneeded organisms like genotype and phenotype because natural selection weeds out populations by their traits. Evolution is made to change populations over time.
10. None
