You have collected and determined genotypes of 200 individuals from a population of thr fruit fly, Drosophila pseudoobscura. Your sequencing study revealed 20 individuals with genotype AA, 70 individuals with genotype Aa and 110 individuals with genotype aa. i) what are your theoretical expectations for the number of individuals with each genotype if the population is in Hardy-Weinberg equilibrium. ii) Based on the genotype counts observed, is there evidence that this population of fruit flies deviates from your theoretical expectations under Hardy-Weinberg equilibrium?
PLEASE HELP!! A. Calculate the recessive allele frequency for both original and isolated populations. ___ B. The null hypothesis was that these flies would remain at H-W equilibrium once they were isolated. The researchers ran a chi square on them using 0.05 significance. C. What is the D.F. value= ___ D. What is the Critical Value from the probability table? ___ E. Null hypothesis accepted? ____
A dominant mutation in Drosophila called Deltacauses changes in wing morphology in Delta/+ heterozygotes. Homozygosity for this mutation (Delta /Delta) is lethal prior to the adult stage. In a population of 150 flies, it was determined that 60 hadnormal wings and 90 had abnormal wings.a. What are the allele frequencies in this population?b. Using the allele frequencies calculated in part (a),how many total zygotes must be produced by thispopulation in order for you to count 160 viableadults in the next generation?c. Given that there is random mating, no migration,and no mutation, and ignoring the effects ofgenetic drift, what are the expected numbers ofthe different genotypes in the next generation if160 viable offspring of the population in part(a) are counted?d. Is this next generation at Hardy-Weinberg equilibrium? Why or why not?740 Chapter 21 Variation and Selection in Populations
Based on this information (picture) A. What is the probability that a randomly sampled individual from the population has two copies of the a allele (that is, that it has an aa genotype)? B. What is the probability that both members of a randomly sampled married couple (man and woman) are aa at the asparagus-smelling gene? C. What is the probability that both members of a randomly sampled married couple (man and woman) are heterozygotes at this locus (meaning that each person has one allele A and one allele a)? D. Consider the type of couple described in (c). What is the probability that the first child of such a couple also has one A allele and one a allele (is a heterozygote)? Remember that the child must receive exactly one allele from each parent.
A researcher sequences the Pitx1 gene in a population of 100 stickleback fish that is known to affect dorsal spine length. He finds that the gene is NOT in Hardy-Weinberg equilibrium. There is an excess of homozygotes compared to expected. He then sequences 5 more loci scattered across the genome (on different chromosomes) but finds that these other loci are all in HW equilibrium. (That is, there was no difference between observed and expected frequencies). What is the most reasonable conclusion concerning the Pitx1 gene?
Upon further genetic study of the skunk population, you find the following numbers of haplotypes across the population: AB = 400, Ab = 600, aB = 800, ab = 200. Calculate D (the extent of linkage disequilibrium) for each haplotype. 4) What processes or features might cause the results you observed in part 3 of this question? Give two possibilities
a. Two linked biallelic loci (c = 0.1) have allele frequencies pA = 0.7 and pB = 0.4. If these two sites are in linkage disequilibrium with D = -0.12, what are the expected haplotype frequencies under these conditions? b. What will the linkage disequilibrium parameter D be after 20 generations?
5. In a population genetic study of a species of California wild oat, the following genotype frequencies were found for a trait (hairiness of the leaf sheath) which is controlled by a single locus: HH 0.571 Hh 0.071 hh 0.358 a) What are the expected frequencies of these genotypes under Hardy-Weinberg? b) Calculate F. c) Briefly explain what the value in b) implies regarding heterozygosity and suggest what might be going on in this population to explain this result.
Approximately 1% of the magpies (Pica pica) in a hypothetical populations are albino. Assume that the albino phenotype is due to a recessive allele and that this population is in HardyWeinberg proportions at this locus. (a) What is the estimated frequency of the albino allele in this population? (b) What is the probability that the first progeny born to a mating between an albino and a normal magpie from this population will be albino? (Hint: what is the probability that the normal magpie is heterozygous, given the allele frequencies in this population?)

A population sample of 300 individuals is studied for the electrophoretic mobility of an enzyme that varies according to the genotype determined by 2 alleles, E and T of a single gene. The results are 7 individuals with genotype EE, 106 with genotype ET, and 187 with genotype TT. What are the allele frequencies of E and T, and what are the expected numbers of the 3 genotypes if random mating is assumed?
You discover a new X-linked mutation for antenna shape in Drosophila (fruit flies) which produces long antennae. You call this new allele long (XL2), and discover it is incompletely dominant with the short antennae allele (XL1), meaning that heterozygotes have antennae that are intermediate in length. In your laboratory population, 9% of the males have long antennae. Assuming your population is in Hardy-Weinberg equilibrium, what proportion of females would you expect to have intermediate antennae? Answer choices: 0.50 0.90 0.83 0.0081 0.16
