Many species of birds choose their mates based on how brightly colored they are. If feather color is heritable, how would this violate the assumptions required for a population to be in Hardy-Weinberg equillibrium? HW equilibrium would cause mutations in such a species. A. This is a founder effect В. This is a bottleneck effect C. OD. Mating is non-random. Alleles for brightly colored phenotypes might become more common in the species and allele frequency would change.
Under genetic drift, if an allele’s frequency is 1%, what is the likelihood that it will be lost from the population? part B; Construct a graph that describes the likelihood of fixation of a particular allele, for a small population that is under Wright-Fisher genetic drift. Don’t forget to label axes completely.
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…
A group of four birds flies to a new location and starts a newcolony. Three of the birds are homozygous AA, and one bird isheterozygous Aa.A. What is the probability that the a allele will become fixed in thepopulation via genetic drift?B. If fixation of the a allele occurs, how long will it take?C. How will the growth of the population, from generation togeneration, affect the answers to parts A and B? Explain.
A new species of snail was discovered. Your initial population genetics survey found that fA:0.48. To determine the primary mode of reproduction you survey the population again in one generation. You collect 100 individuals in the next generation. The composition of your collection is AA=38, Aa=20, aa=42. What is the primary mode of reproduction? a. random mating b. not enough information to determine c. nonrandom mating due to inbreeding
Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations. Fitness CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0 Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Based on the table, how would you expect the frequency of C to change over time in population 1? Group of answer choices A.) frequency of C will increase B.) frequency of C will decrease C.) frequency of C will stay the same D.) frequency of C will change randomly
A group of four birds flies to a new location and initiates a new colony. Three of the birds are homozygous AA, and one bird is heterozygous Aa. A. What is the probability that the a allele will become fixed in the population via genetic drift? B. If fixation of the a allele occurs, how long will it take? C. How will the growth of the population, from generation to generation, affect the answers to parts A and B? Explain.
A population of birds may have red feathers Show work here: (the dominant phenotype) or orange feathers (the recessive phenotype). Red feathered birds have the genotype RR or Rr. Orange feathered birds have the genotype r. The fequency of the RR genotype is 46. a. What is the frequency of heterozygous birds? b. What is the frequency of the R allele? c. What is the frequency of the r allele?

There is an outbred population of mice living in a farmer’s field. Mutations occur at a genecalled nurseryrhyme that cause a totally recessive form of blindness (h=0). These blind micedo not survive to reproduce because the farmer’s wife cuts off their tail (and other bits) witha carving knife. Surveying the field for baby mice you find that 3/10,000 mice are blind.A. Assuming that the population mates at random, what is the mutation rate of blindnesscausing alleles?B. Following more careful study you now find that there is actually a 20% reduction in theviability of heterozygotes for these mutations. What would you now estimate as themutation rate for this gene?
The gene pool of the peppered moth population in England changed. As a result, the frequency of the black allele in the population increased, while the frequency of the white allele decreased. Which of the following statements correctly describes why the allele frequencies changed in the peppered moth population? a The white moths die more often compared to the black moths due to the random mutation in the lichen population. b The white allele became less common as a result of sexual selection. Black moths reproduced more often due to the female preferring dark colors to light colors. c Black soot from the burning of coal discolored the bark of local trees; black moths became more common because they blended in better, and survived to reproduce more often than white moths. d The industrial revolution in England produced a harmful chemical toxin that killed the white moths, but did not affect the black moths.
