Question

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than in large populations. O No. In the ferret experiments, allele frequencies changed more quickly in the large populations than in small populations. Check Answer Q3.4. So far in this lab, you have learned about sampling error and sample size, and how these relate to the phenomenon of genetic drift. Based on what you've learned, which statement below best explains the relationship between population size and the rate of evolution by genetic drift? Smaller populations are at greater risk of extinction. They have more frequent mutations, because they need to evolve more quickly to survive. In smaller populations, a predator with a preference for light or dark ferrets can easily cause large changes in allele frequency. These changes accumulate quickly over time. In smaller populations, each generation's zygotes represent a small sample of gametes from the gene pool; therefore, smaller populations exhibit greater differences in allele frequency over time. Check Answer Q3.5. Why does something unique happen in every population (and every simulation run)? O Genetic drift is the adjustment of each population to its environment. Because every population lives in a unique habitat, it shows a unique pattern of evolutionary change. O Genetic drift can occur in every generation in every population, just by random chance. With so many chance events in play, every population evolves differently. Genetic drift is evolution that is unpredictable. The only way for evolution to be unpredictable is if something different happens with every population at every opportunity. O Genetic drift is the movement of genes between populations. Because model ferrets move at random, the movement of genes is random too—and therefore unique in every run.

Answer 1

Ang No, in ferret experiment, allere feequency changed more quickly in small population than longe population Genetic drift operate on small population. It is vandom change in allele frequency that may lead to cost of allell or fixation of allele while natwal Selection occur on large po pulation that change the alle option c ºs correct ICIRTUIGIN'ZUUTUU, VUJV TUU
