analysis questions: 1. explain why the frequency of the alleles in simulation 1 did not change although the number of different phenotypes did change. 2. why did the frequency of the alleles change in simulation 2? 3. in simulation 3, the frequency of the alleles should have changed due to the random event that removed a portion of the population. a. how was simulation 3 different from simulation 2? b. if the class size had been 1,000 students instead of 24, and the same students were randomly removed, do you think the change in allele frequency would have been as different as the change your class experienced?

Question

Accepted Answer

### Question 1
# Brief Explanations:
In Simulation 1, allele frequency stays constant because the process (like random mating without selection, mutation, migration, or genetic drift) preserves allele proportions. Phenotype change may come from phenotypic plasticity or environmental - induced phenotypic variation without altering allele frequencies (e.g., a trait with the same alleles showing different phenotypes due to environment).
# Answer:
Allele frequency didn't change as the processes maintaining allele proportions (no selection, mutation, migration, drift) occurred, while phenotype change was due to non - genetic (e.g., environmental) factors affecting phenotype expression.

### Question 2
# Brief Explanations:
In Simulation 2, allele frequency changed likely due to evolutionary forces. For example, natural selection (certain phenotypes/genotypes had higher survival/reproduction, changing allele proportions), mutation (new alleles introduced), migration (alleles added/removed), or non - random mating (altering allele combinations in the gene pool).
# Answer:
Allele frequency changed because an evolutionary force (e.g., natural selection, mutation, migration, non - random mating) acted, altering the proportion of alleles in the population.

### Question 3a
# Brief Explanations:
Simulation 3 likely involved a random event (like a bottleneck, random removal of individuals) while Simulation 2 may have had a non - random force (e.g., selection based on phenotype/genotype fitness). So Simulation 3's allele frequency change was due to random sampling (genetic drift from a random event), unlike Simulation 2 which may have had directed change (e.g., selection).
# Answer:
Simulation 3's allele change was due to a random event (e.g., bottleneck, random population removal - genetic drift), while Simulation 2 likely had a non - random force (e.g., selection) driving allele change.

### Question 3b
# Brief Explanations:
Genetic drift (the change due to random events) has a stronger effect in small populations. A class of 24 is small, while 1,000 is large. In a large population, the same number of random removals would have a smaller relative impact, so the allele frequency change would be less different (smaller in magnitude) than in the small (24 - student) population.
# Answer:
No. Genetic drift is stronger in small populations. A 1,000 - student population is large, so the same random removals would have a smaller relative impact, resulting in a less pronounced change in allele frequency.
