Which parameter from the software must you adjust in order to give a "selection advantage" to organisms with particular phenotypes? Select one. 1. Starting frequency of allele A1 2. Fitness of genotype A1A1 3. Mutation rate from A1 to A2 4. Fraction migrants each generation 5. Population size 6. Inbreeding coefficient (F)
What are some notes or take aways about this model? Model 1 – PopGen Fish Pond This model is an agent-based population genetics simulation. The program contains the tools to conduct virtual experiments violating all the assumptions of Hardy-Weinberg theory (small population, selection, mutation, migration, and non-random mating).
The following gel represents a result of the RFLP experiment you designed using the DNA of 9 different individuals (this is your population). The ladder used is a 50bp ladder and is loaded in the first well. 1. What is the percentage of non-tasters in this population? 2. What is the percentage of heterozygous in this population? 3. What is the frequency of nontaster allele in this population? 4. What is the frequency of the taster allele in this population?
Consider a sample of 100 individuals sampled from a population in Hardy-Weinberg equilibrium that are genotyped at a single locus. Of these 100 individuals, 25 individuals are A¡A1, 45 are A1A2, and 30 are A2A2. What is the actual (observed) allele frequency of the A1 allele in this sample? (you may use a calculator if needed) O A. 0.325 O B. 0.275 O C. 0.475 O D. 0.525
The plots show changes in the frequency of allele A1 during population genetic simulations (allele frequency through time plots). The sets of runs in the two panels differed in only one variable. What was the difference? 100% 80% 60% 40% 20% 0% 0 1000 2000 3000 4000 O The A1 mutation rate was less on the right O Balancing selection slowed the increase in A1 frequency on the right O Selection is weaker in the right panel O Selection is stronger in the right panel 5000 6000 7000 100% 80% 60% 40% 20% 0% 0 1000 2000 3000 4000 5000 6000 7000
In this version of the simulation (500 population size; 500 carrying capacity), all fish are equally likely (though not 100% likely) to survive and reproduce. There are no mutations, nor are there any entering or leaving the population. When they reproduce, they choose a mate from the pool at random and produce ten offspring by chance with the probability of the offspring’s genotypes determined by the punnett square. What caused the allele frequencies to change and vary in the trials? (ex attached).
You are examining a scorpion population within the Las Vegas area. Your field team is able to capture 200 yellow scorpions and 450 brown scorpions. You know that the color brown (B) is dominant over the color yellow (b). Based on this information, please answer the following questions. Be sure to show your work. • What is the allele frequency of each allele? • What percentage of scorpions in the population are heterozygous?
In a population of 500 fruit flies, 250 are genotype RR, 100 are genotype Rr and 150 are genotype rr. Determine the allele frequencies for this gene in this population. Remember that the frequencies should add to 1. Please show your work.
1. Certain flowers are either red (dominant) or white (rr). 91% of the flowers are red. Using the equations, calculate the frequency of the R allele. First you replace R and r for p and q. Thus we know that q2 = .09, because only the homozygous recessives will be white. *changed away from percentages to work the math more easily* What is the frequency of the R allele in this population? 2. In a coastal city in Nigeria, the incidence of Sickle-Cell disease is 4% of the population. Based on this information, what is the frequency of this allele in the population of that city? 3. In a given human population, only the "A" and "B" alleles are present in the ABO system; there are no individuals with type "O" blood or with O alleles in this particular population. If 200 people have type A blood, 75 have type AB blood, and 25 have type B blood, what are the alleleic frequencies of this population (i.e., what are p and q)? 4. An allele W, for white wool, is dominant over allele w, for…
77)Each graph below shows the frequency of the A allele in six simulated populations (each line in a graph) over 500 generations. Each of the six simulations within a graph were done with the exact same settings of relative fitness among the genotypes and population size BUT these settings differed between the four graphs. Which graph shows a situation in which the effect of selection is the highest relative to the effect of drift? C D A B
