What can you conclude about genetic variation and population size? Chose all answers that are true. O As population size decreases, the likelihood of losing alleles increases. O Smaller populations are more like to lose genetic diversity due to drift than larger populations. O Smaller populations lose alleles more quickly, in less generations, than larger populations. O Both allele fixation and allele loss represent loss of genetic diversity.
Under idealized Hardy-Weinberg conditions, which of the following is FALSE? [1] O mutation rates will increase with each generation O no new alleles would be added to the population's gene pool O there will be no change in alelle frequencies in a population over time O the population is so large that random affects don't change allele frequencies all of these are true
Hot water near volcanoes ers ences line A population of wildflowers consists of two flower colors. Yellow flowers (C^y) are completely dominant to white flowers (C^w). If the frequency of the C^y allele is 70%, what is the frequency of the C^w allele?* ods 1 and 2 70% Highschool MP3, 30% 35% 65% Fri Stanley Miller and Harold Urey created an experiment that simulated conditions on early Earth. Building on the results from this experiment, scientists decide to test the effect of varying the initial amount of NH3 on monomer formation. They set up the same simulation with the exception of starting with three different
Of the statements provided, which one is true for Hardy-Weinberg Equilibrium (HWE)? O The population is evolving due to genetic drift. O Natural Selection is not occuring within the population. Op+q=1 calculates genotype frequencies. O Individuals within the population move back and forth between another nearby population.
Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?

Gene flow often increases genetic diversity of populations that come together. Which of these is an example of when gene flow could reduce genetic diversity if two populations (Population A and Population B) come together? O The offspring with parents from population A and B have low survival because they are not adapted to the environment. O Individuals from population A have an allele that is not found in population B. O Individuals from population B have an allele that is not found in population B O Population A only has homozygous recessive alleles and population B only has homozygous dominant alleles.
If allele frequencies are changing over generational time, what can we say about this population? (Check all that apply) O The population is finite OThe population is evolving The population is experiencing mutation O The population is under Natural Selection
Small population size causes genetic drift because ofchance sampling of different alleles from one generation to the next. We can predict how much geneticdrift occurs for a given population size using binomialsampling statistics. With a population of size N, wecan estimate that 95% of the time the allele frequency(p) in the next generation will be withinthe confidence interval of p ± 1.96 (√p(1 − p)2N ),where p(1 − p)2Nis an estimate of the statistical variancein allele frequencies from one generation to the nextwith random sampling of 2N alleles each generation. a. What is the confidence interval for p = 0.5 whenN = 100,000?b. What is the confidence interval for p = 0.5 whenN = 10?c. How are the results in parts (a) and (b) related tothe consequences of a population bottleneck?
Populations in Hardy-Weinberg equilibrium show no change in allele frequencies from one generation to the next, assuming that certain conditions are met. Which condition is being violated in this image? *** O No gene flow O No genetic drift O No mutation O Random mating 4
If both the forces of mutation and natural selection are acting on this population from generation to generation (and have been acting on this population for many many generations), what do you predict will happen to allele frequencies over successive generations? Allele frequencies will remain constant The frequency of the D allele will increase The frequency of the d allele will increase
Random events are know to contribute to changes in allele frequencies. Do these random events typically play a greater role when the population size is large or small?
