Answer #1

The answer is

(a) It is more potent in a population with small numbers than in a population with large numbers.

Genetic drift is the change in the frequency of an existing gene variant in a population because of random sampling of organisms. Typically in small populations, genetic drift occurs. Genetic drift is more significant in small populations as it has less variation and so a lower ability to respond favorably.

    Select all of the statements about genetic drift that are true. It can cause alleles to be lost in a population by chance. Genetic drift causes allele frequencies to change because only the strongest individuals in a population are reproducing Its strength is proportional to the size of a population -the larger the population, the greater the force Smaller populations experience greater changes in allele frequency due to genetic drift than large populations. It is a random process with respect...

    Genetic drift can be an important evolutionary process. This is due to the fact that (A natural selection acting on the genetic variation of a large population B small isolated populations are unable to defend themselves from predators, therefore they loos genetic diversity. Natural selection, in this case, has less variation to work with. C when genetic drift is the only evolutionary process at work, one allele may be lost forever and the other may become fixed (100% frequency). D)...

    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...

    Questino 7. How I genetic drift different from natural selection? A. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B. Natural selection has a stronger effect in large population, whereas genetic drift acts primarily in small populations. C. Natural selection is a mechanism of evoltion, whereas genetic drift is not a mechnaism but an outcome of evolution. D. Natrual selection tends to cause very rapid evolution whereas gentic drift tends to...

    Read just the long paragraph below and explain in your words the hypothesized evolutionary processes (note, more than one are in play) proposed to remove slightly deleterious alleles from the gene pool. Keep in mind the importance about balance between mutation rates and the consequences to individual fitness. "At first sight, it appears paradoxical that nearly neutral mutations in essential immune genes will be efficiently removed from the species’ gene pool despite having no easily discernible impact on the immune...
