- QUESTION 12 Apopulation is experiencing only selection Allele A1 is favored by selection and starts at a frequency of 03. Which of the following statement(s) islare correct? (Mark al that apply) O The effects of selection will be stronger if the population is small D Allele A1 will go to fixation O Allele At wil change randomly in frequency O Allele A2 is more likely to go to foxation than allele A1 O The effects of solection will be stronger if the population is largeQuestion 23 What is the MOST LIKELY explanation for why there is variation in aging across different species? O The strength of selection is determined by aging O Trade-offs only apply to some species O Mutation accumulation theory applies to some species while antagonistic pleiotropy applies to others O Different species suffer different levels of background (i.e., extrinsic) mortalityQuestion 18 When fitness is lower at both extremes of phenotypic variation for a trait (e.g., the very largest and very smallest beaks in a bird population) than for the median value in a population, the predominant evolutionary force at work is called Group of answer choices Only 1 correct answer phenotypic selection stabilizing selection directional selection phenotypic choice

Observed number of each genotype ■ ● A1A2 =20 A2A2 = 40 ● A₁A1=36 A1A2=28 A₂A2=36 Note that raw numbers are given. The question is whether observed frequencies = expected frequencies. You must first compute the genotype frequencies.

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).
