Gene flow often increases genetic diversity of populations that come together. Which of these is an example of when gene flow could reduce genetic diversity if two populations (Population A and Population B) come together? O The offspring with parents from population A and B have low survival because they are not adapted to the environment. O Individuals from population A have an allele that is not found in population B. O Individuals from population B have an allele that is not found in population B O Population A only has homozygous recessive alleles and population B only has homozygous dominant alleles.

In a hypothetical species of mice, the shaggy gene determines hair length. S is the dominant allele and confers the short hair phenotype. Homozygous ss individuals have long hair. There are 422 long-haired mice and 278 short-haired mice in the population. How many shaggy gene alleles are in this population? a- 700 b- 350 c- 2800 d- 1400
After some time, individuals begin to migrate between islands 2 and 3, but the overall population size remains at 40 individuals on each island. On island 3, you would expect that the red allele frequency will decrease, but the yellow and blue allele frequencies will increase over time. Select one: O True O False After many generations, you return and sample individuals from the mainland coastal region and island 2, and you discover that the same mutation, a green allele, has appeared in both populations. It is present in five individuals in the mainland population and in five individuals in the population from island 2. True or False? Mutation is a stronger evolutionary mechanism in the large mainland population than in the small island population. Select one: O True O False
How can gene flow impact a population's allele frequencies? Choose one of the following: By causing mutations in the DNA By introducing new alleles through migration By wiping out a large proportion of the population
In a population of mayflies, variation in the STRIPE gene causes different body coloration. SS individuals have skinny stripes, Ss individuals have wide stripes, and ss individuals are unassigned. You collect some mayflies and estimate that the frequency of the S allele is 0.85. You want to know whether the population is evolving, so you will return to the same site next summer and collect 1000 mayflies from the next generation. If the population is not evolving, how many of the 1000 mayflies collected next summer should have wide stripes. (round to the nearest whole number) A. 255 b.850 C. 723 D. 23
In which of the following pairs do both evolutionary processes introduce new genetic variation into a population? a. natural selection and genetic drift b. mutation and gene flow c. natural selection and gene flow d. gene flow and genetic drift
Galapagos medium ground finches are found on Santa Cruz and San Cristóbal islands, which are separated by about 100 km of ocean. Occasionally, individuals from either island fly to the other island to stay. This can alter the allele frequencies of the population through which of the following mechanisms? a. natural selection b. genetic drift c. gene flow d. mutation
After 10,000 generations, this population becomes fixed for allele A. What is the frequency of the recessive allele a if the population is fixed for the dominant allele A? Generation 2 3 4 dominant (A) 0.5 0.8 0.3 0.9 0.6 recessive (a) 0.5 0.2 0.7 0.1 0.4 O 0.4 100 0.24 0.6
If both the forces of mutation and natural selection are acting on this population from generation to generation (and have been acting on this population for many many generations), what do you predict will happen to allele frequencies over successive generations? Allele frequencies will remain constant The frequency of the D allele will increase The frequency of the d allele will increase
Natural selection acts on phenotypes within a population. As a result, over time, the phe- notypic frequencies in a population can change. The graph below shows how the pheno- type of a population changed after selection occurred. Number of Individuals B Value of Phenotype A graph that shows how phenotypic frequency changed before and after selection. с population after selection Which of the following scenarios would most likely result in the phenotypic change shown in the graph above? D original population A A population of rats live on the ground and in short trees. A tree-dwelling snake that preys on the rats is introduced into the area. Warming of the arctic tundra reduces the average snow cover that lighter-colored arctic foxes rely on for camouflage. Darker-colored arctic foxes are better suited to the ex- posed moss and grass habitat. Robins that lay smaller-than-average clutches of eggs produce fewer viable offspring, while larger-than-average clutches of eggs result in…
Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?
Which of the following examples does not match the given term? The Founder effect - two populations of birds from two different islands occasionally cross over on these islands to mate with each other. Gene flow - A group of fish is introduced to a neighbouring population and begin to reproduce with the resident fish Inbreeding- a mice with the genotype aa inherited both allele copies of a from the same grandparent. Population bottleneck - a populátion of frogs experiences a coldsnap which kills 75% of the population.
What can you conclude about genetic variation and population size? Chose all answers that are true. O As population size decreases, the likelihood of losing alleles increases. O Smaller populations are more like to lose genetic diversity due to drift than larger populations. O Smaller populations lose alleles more quickly, in less generations, than larger populations. O Both allele fixation and allele loss represent loss of genetic diversity.
