Bio 351 Fall 2023 Problem Set 3 You are breeding a model organism in the lab. You decide to start a new culture by taking 10 individuals from a larger populaƟon, allowing only these 10 individuals to reproduce to start a new populaƟon. Using the DriŌ tab of the Excel sheet, generate your starƟng sample of 10 individuals. Copy and paste the genotypes and phenotypes of the 10 individuals here: Sample Randomly Generated Based on Allele Freqs Locus A1 A2 Genotype Phenotype Color B B BB Red Pattern D D DD Solid Antennae E F EF Simple branched Y Wings G G GG Wings Color B B BB Red Pattern D D DD Solid Antennae F F FF Straight | Wings G G GG Wings Color A A AA Blue Pattern D D DD Solid Antennae F F FF Straight | Wings G G GG Wings Color A B AB Purple Pattern C C CC Striped Antennae E F EF Simple branched Y Wings G G GG Wings Color A B AB Purple Pattern C C CC Solid Antennae F E FE Simple branched Y Wings G G GG No wings Color B A BA Purple Pattern D D DD Solid Antennae F F FF Straight | Wings G G GG Wings Color B B BB Red Pattern D C DC Spotted Antennae E F EF Simple branched Y Wings G G GG Wings Color A B AB Purple Pattern D D DD Solid Antennae F E FE Simple branched Y Wings G G GG Wings Color B A BA Purple Pattern D C DC Spotted Antennae E E EE Feathered ¥

You change the diet given to your organisms, making all pigments more “costly” for organisms to produce, and find the following relaƟve fitness for each genotype: o Striped (CC) 0.5, SpoƩed (CD) 1, Solid (DD) 0.25 StarƟng with your final allele frequencies from your last generaƟon of driŌ, use the SelecƟon tab of the spreadsheet and input your allele frequencies. Then, change the fitness by genotype of the target locus appropriately to esƟmate the change in this allele frequency for the next generaƟon. Plug these values in, then generate your next sample, and repeat for a total of 5 generaƟons of selecƟon. Keep track of how the other loci change randomly with regards to allele frequencies.

Bio 351 Fall 2023 Problem Set 3 ReflecƟon Write a few short paragraphs about the trends you observed throughout these simulaƟons. Think about how your genotype and allele frequencies changed under different scenarios, whether you saw anything unexpected, and what you think are some limitaƟons of this kind of simulaƟon. AŌer the first generaƟon, I hardly saw any changes in the frequency for color and antennae, which is surprising because I thought that aŌer a few generaƟons, natural selecƟon would select different allele variaƟons. When observing the trends, I also realized that the lines on the graphs would be parallel unƟl a certain generaƟon then it would overlap then decrease and then increase. Some limitaƟons to this kind of simulaƟon would be human error, most of the Ɵme I had to start over with my data because I made mistakes. Secondly, sample size can be too small or large which would give inaccurate data. 0 0.2 0.4 0.6 0.8 1 2 3 4 5 6 A1 Frequency Generation Color 0 0.2 0.4 0.6 1 2 3 4 5 6 A1 frequency Generation Pattern 0 0.5 1 1 2 3 4 5 6 A1 frequency Generation Antennae
