Genetic drift is a change in allele frequencies due to random chance across generations is more likely in large populations has a likely result of driving allele frequencies to 50/50 can result in allele fixation or loss especially in small populations

Is selection more "predictable" than genetic drift? Why? If not, why not? yes, under drift, any allele may increase or decrease in frequency no; selection always removes deleterious alleles while drift always fixes them no; under drift, recessive alleles are always lost from the population no; under genetic drift, dominant alleles are fixed yes; under selection, dominant alleles increase in frequency yes; under selection, alleles that reduce offspring production increase in frequency no; selection always fixes advantageous alleles while drift makes populations more similar

From the list provided, please select those that are associated with the concept of genetic drift. Each correct answer is worth 3.3 points. Each incorrect answer will result in the loss of 1 point. Allele frequencies that change due to random chance. Founder effect Genetic bottlenecks Movement of alleles that equalizes gene frequencies. Hybridization Mutation

Assume there is a dominant allele that causes infertility in 20% of the individuals who inherit it. What will happen to the frequency of that allele in the population over time, and why?
