You are studying a population of 1000 skunks (which are diploid). You sample alleles at two genetic loci, A and B. The A gene has two alleles A and a, and B has two alleles B and b. The frequency of the A, a, B, b alleles are p, q, r, s respectively, so that p = 0.2, q = 0.8, r = 0.3, s = 0.7. 1) Calculate the expected genotype frequencies of all possible genotypes under Hardy-Weinberg equilibrium. 2) Calculate the expected haplotype frequencies of all possible haplotypes assuming the two loci are unliked.
A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotypre is .35 What is the frequency of the heterozygous rabbits? What is the frequency of the B allele? What is the frequency of the b allele?
There is a gene that causes people to have crumbly earwax. This gene is expressed as a complete dominant: Individuals who are homozygous dominants (CC) or heterozygous (Cc) have crumbly earwax. Homozygous recessives (cc) have gooey earwax. There are 100 people, 64 of whom have crumbly earwax. Assuming Hardy-Weinberg conditions, what is the frequency of the c allele on Paradise Island? Group of answer choices 0.80 This cannot be answered without more information. 0.60 0.36 None of the above.
Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
In a certain population of mice, a single gene controls fur color. There are two possible alleles: B, which leads to a black fur, and W, which leads to white fur. Individuals with the genotype BB will have a black fur, individuals with the genotype WW will have white fur, and individuals with the genotype BW will have gray fur. Scientists recorded the fur color of 1,000 mice from the population. They found that 200 mice have black fur, 400 have gray fur, and 400 have white fur. Ten years later, the measurements are repeated. Again, they recorded the fur color of 1,000 mice. They found that 400 have black fur, 400 have gray fur, and 200 have white fur. Part A: Show the Hardy-Weinberg calculations for the beginning and ending populations. Include the values for the equation as well as the p and q values. Show your work. Part B: Use the Hardy-Weinberg calculation to explain if this population is evolving or not. Then propose a hypothesis about the environment of these mice that would lead…
You are studying three traits in a goldfish variety; body colour (A or a), tail length (B or b) and shape (C or c). Note: Use the uppercase letters for the alleles associated with the dominant phenotypes and the lowercase letters for the alleles associated with the recessive phenotypes. Assume that each of these traits is regulated by one gene. Photo credit https://www.petmd.com Part A. You mate a gold fish (P1) with a white fish (P2) and obtain 100 fish in F1, of which 50 are gold and 50 are white. Write two sets of the possible genotypes of the parental and the resulting F1 fish by filling in the table below. Sets P1 P2 F1 gold fish F1 white fish 1 2 Part B. You cross a true breeding gold fish having long curly tail (P3) with a true breeding gold fish having short and straight tail (P4). All of the resulting F1 fish have long straight tails. Write the genotype of the parental fish (P3 and P4) using the outlined nomenclature.…
A mountain region has a population of 5,000 mountain goats. You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive. A deadly virus infects all of the RR mountain goats in the population (above), killing all individuals of this genotype and leaving the population with only the rr and Rr mountain goats. a) Calculate the new allele frequencies for this population. Show your work. b) Calculate the new (observed) genotypic frequencies for this population. Show your work. c) Does this population still appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).
Let’s suppose that pigmentation in a species of insect is controlledby a single gene that exists as two alleles, D for dark and d for light.The heterozygote, Dd, is intermediate in color. In a heterogeneousenvironment, the allele frequencies are D = 0.7 and d = 0.3. Thispolymorphism is maintained because the environment has somedimly lit forested areas and some sunny fields. During a hurricane,a group of 1000 insects is blown to a completely sunny area. In thisenvironment, the relative fitness values are DD = 0.3, Dd = 0.7, anddd = 1.0. What are the predicted allele frequencies in thenext generation?
In German cockroaches, curved wing (cv) is recessive to normal wing(cv+). Bill, who is raising cockroaches in his dorm room, finds that thefrequency of the gene for curved wings in his cockroach population is0.6. In his friend Joe’s apartment, the frequency of the gene for curvedwings is 0.2. One day Joe visits Bill in his dorm room, and severalcockroaches jump out of Joe’s hair and join the population in Bill’sroom. Bill estimates that, now, 10% of the cockroaches in his dormroom are individual roaches that jumped out of Joe’s hair. What is thenew frequency of curved wings among cockroaches in Bill’s room?

A meadow is home to a population of plants of a particular species. Among these individuals are 125 plants that have red flowers and 375 plants that have white flowers. The allele of the flower color gene that produces red flowers (R) is completely dominant over the white flower color allele (r). If a plant with red flower color is crossed with a plant that produces all white flowers, what is the probability that the offspring will include plants that have white flowers? Group of answer choices a. 50% chance b. 75% chance c. 0% chance d. 25% chance e. There is not enough information to say.
