Which of the following statements about genetic drift as an evolutionary factor is true? a. It is more potent in a population with small numbers than in a population with large numbers. b. It is responsible for the selection of mutations. c. It is connected to the movements of alleles between populations of a single species. d. Its strength is proportional to the size of a population: the larger the population, the greater the force. e. Both a and b

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...

Select the statements that accurately describe the effect of natural selection on genetic equilibrium: a. It can cause allele frequencies in a population to be in genetic equilibrium. b. It can cause a dominant allele for a gene to become more abundant in a population. c. It can cause an allele to become more abundant in a population if it provides a fitness advantage over other alleles for that trait. d. It is an evolutionary force that prevents natural populations...

Which of the following is true about genetic drift? a) it only happens in small populations b) it decreases the genetic variability among populations c) it never results in allele fixation or loss d) it can cause the prevalence of deleterious alleles to drift up and down

Question 3 The cause of genetic drift is sampling error, which occurs when allele frequencies of a chosen subset of a population are the same as those in the total population, by selection when allele frequencies of a chosen subset of a population are different from those in the total population, by chance when allele frequencies of a chosen subset of a population are different from those in the total population, by selection when allele frequencies of a chosen subset...

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...

Question 3 1 pts Which of the following is TRUE about coalescent theory? The coalescent point represents the origin point of a particular allele Loci that are under directional selection exhibit shorter coalescent times than neutral loci in the same population The coalescence time can be used to calculate the mutation rate for a locus O Coalescence times will be shorter in larger populations Question 4 1 pts In a very large population of plants, 50% of AA individuals survive...

Which of the following statements regarding the Hardy-Weinberg Equation is TRUE? Answers: It can only be used when allele and genotype frequencies remain constant across generations in a population It can only be used when allele and genotype frequencies change across generations in a population It has no assumptions It mathematically shows how recessive alleles in a population decrease over time It reveals when allele frequencies change over time in a population Assuming Hardy-Weinberg Equilibrium, what percentage of individuals in...
