Homework Answers
In this case, remember that sampling error occurs when we select a non representative sample from the total population, obtaining a different allele frequency that the total population. So, the correct answer is when allele frequencies of a chosen subset of a population are different from those in the total population, by chance

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...

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...

Q1.3. How do the frequencies of allele S in the Breeding Pens compare to the frequency of allele S among ferrets in the field population? O They are exactly the same as the field population's frequency O They are nearly the same as the field population's frequency (within 10%). O They vary, and some are fairly different from the field population's frequency. (Check Answer Q1.4. How did the frequencies of allele S in the pens come to be different from...

Plase hlp answer these questions:
White wool in sheep is controlled by a dominant allele R, and black wool by the recessive allele r. In an isolated population of 6530 sheep, 514 are black, 4981 are heterozygous, 1035 are homozygous white. When will this population be expected to reach Hardy-Weinberg equilibrium? in the next generation in two generations it already is in equilibrium impossible to tell it will not reach equilibrium A population has the following genotypic distributions: A^M A^M...
