4. Sea anemones - Generations 1-10 A large population of sea anemones lived undisturbed in the ocean shores of Channel Islands for several decades. Due to climate change, an unexpectedly large tsunami has transported larva of sea anemone, to five nearby Islands: Chunky, Jüxi, Carta, Shells, and Natura. The chart below shows the frequency of the nit allele from each population over the first 15 generations. Generation Chunky 0.5 0.5 | 0.2 0.3 0.46 0.5 0.5 0.64 0.65 0.68 Carta 0.5 0.5 0.48 0.47 0.46 Shells 0.43 0.44 0.45 0.49 0.52 Natura 0.5 0.5 0.44 0.36 0.33 0.5 | 0.55 0.58 0.61 0.67 0.72 | 0.67 0.1 | 0.09 0.08 0.07 0.03 0.82 0.7 | 0.77 0.79 0.80 0.81 0.83 | 0.85 0.87 0.78 0.39 0.37 0.34 0.28 0.25 0.23 0.21 0.1 0.03 09 0.92 O 0.8 0.82 .85 13 0 1 0 151 Look at the Generations 1-15 graph of the seagrass. a. Explain which evolutionary force is responsible for the variation in the nit allele frequencies of populations (drift or migration) and how you came to this conclusion. b. In which populations has the nit allele reached fixation? c. What does it mean for an allele to reach fixation? d. Imagine if the Generations 1-15 sea anemone population sizes were significantly larger in Jiivi Island. Assuming all other conditions remained the same, how would the increase in population sizes change the timing of this population reaching fixation for one allele? (Describe this change in general terms. You do not need to calculate any specific numbers.) 5. Koala (Phascolarctos sinereus) Due to wildfires, the population of koalas was reduced to 15 individuals at the end of the 20th century. Since then, their population size has rebounded to over 10,000. What is the most likely long-term effect of wildfires on the koala population? The population has high allelic diversity b. The individuals are genetically similar c. The new population has allele frequencies similar to the original population as the koala pop size has recovered d. The population is more likely to survive disease e. Mutations are more frequent in new population

Answer 1

A. Genetic drift is responsible for variation in the ni+ allele because genetic drift is caused by the climate change.

B. In chunky, jivi and shells reached fixation.

C. Accordind to hardy weiberg principle value 1 means stability
