In Drosophila melanogaster, wing shape is an autosomal trait. Vestigal wing is recessive (v) to the dominant trait for the normal long wings (V). In a mainland source population, the allele frequency of v is 0.02 . A small, experimental population of 100 flies was introduced on an island and had 20 flies with vestigal wings and 40 heterozygotes. What are the allele frequencies of V and v in this introduced population? What proportion (%) of heterozygotes and homozygous recessive flies would you expect to see after a few generations of mating on this island? What phenomenon of population genetics does this experiment demonstrate? p+q=1, p^2+ 2pq+q^2 = 1

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 sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
Two chromosome inversions are commonly found in populations ofDrosophila pseudoobscura: Standard (ST) and Arrowhead (AR). Whenthe flies are treated with the insecticide DDT, the genotypes for theseinversions exhibit overdominance, with the following fitnesses:Genotype FitnessST/ST 0.47ST/AR 1AR/AR 0.62What will the frequencies of ST and AR be after equilibrium has beenreached?
. In 1919, Calvin Bridges began studying an X-linkedrecessive mutation causing eosin-colored eyes inDrosophila. Within an otherwise true-breedingculture of eosin-eyed flies, he noticed rare variantsthat had much lighter cream-colored eyes. By intercrossing these variants, he was able to make a truebreeding cream-eyed stock. Bridges now crossedmales from this cream-eyed stock with true-breedingwild-type females. All the F1 progeny had red (wildtype) eyes. When F1 flies were intercrossed, the F2progeny were 104 females with red eyes, 52 maleswith red eyes, 44 males with eosin eyes, and14 males with cream eyes. Assume that thesenumbers represent an 8:4:3:1 ratio.a. Formulate a hypothesis to explain the F1 and F2results, assigning phenotypes to all possiblegenotypes.b. What do you predict in the F1 and F2 generations if the parental cross is between truebreeding eosin-eyed males and true-breedingcream-eyed females?c. What do you predict in the F1 and F2 generationsif the parental cross is…
An allele of the G6PD gene acts in a recessive manner to cause sensitivity to fava beans, resulting in ahemolytic reaction (lysis of red blood cells) afteringestion of the beans. The same allele also confersdominant resistance to malaria. The heterozygote hasan advantage in a region where malaria is prevalent.Will the equilibrium frequency (qe) be the same foran African and a North American country? Whatfactors affect qe?
In the plant Lotus corniculatus, cyanogenic glycoside protects againstinsect pests and even grazing by cattle. The presence of this glycoside inan individual plant is due to a simple dominant allele. A population of L.corniculatus consists of 77 plants that possess cyanogenic glycoside and56 that lack the compound. What is the frequency of the dominant allele responsible for the presence of cyanogenic glycoside in this population?
In 1911. Thomas Hunt Morgan collected the following crossover gene frequencieswhile studying Drosophila. Bar-shaped eyes are indicated by the B allele, andcarnation eyes are indicated by the allele C. Fused veins on wings (A) and scallopedwings (S) are located on the same chromosomes
In the fly speciation experiment described in class, Drosophila from a single culture was split into four isolated cultures, 2 raised on maltose food and two on starch food. After forty generations all possible crosses were done between maltose and starch flies and between the two starch populations. Flies from different food types had very low mating frequencies compared to flies from the same food type but flies from different starch populations only mated at a very slightly lower rate than flies from the same starch population. How would you interpret this finding? Group of answer choices A. allopatric speciation is more powerful than sympatric speciation B. flies are incapable of evolution C. drift causes divergence more rapidly than selection D. sympatric speciation is more powerful than allopatric speciation E. selection causes divergence more rapidly than drift

A dominant mutation in Drosophila called Delta causes changes in wing morphology in Delta/Delta+ heterozygotes. Homozygosity for mutant alleles (Delta/Delta) is lethal prior to the adult stage. In a population of 150 adult flies, it was determined that 60 had normal wings and 90 had abnormal wings. What is the frequency of the mutant Delta allele in this population?
Suppose you want to develop a population of Drosophila thatwould rapidly learn to avoid certain substances the flies coulddetect by smell. Based on the heritability estimate you obtainedin Problem 17, do you think it would be worth doing this by artificialselection? Why or why not?
Entomologists at the New York State Department of Agriculture are interested in determiningthe connection between pest insects infesting crop plants with populations of the same insect-infesting native plants in natural habitats. Long-term trapping and monitoring studies have estimated that on average 3% of the populations move between habitats (farm to natural and vis versa) each generation. A new insecticide resistance allele (∆K) has begun to increase in frequency in agricultural populations. A genotyping survey at this locus of 50 individuals in each population has revealed the following genotype counts:4a. Based on the effects of migration alone, what will the frequency of ∆K be in the forestpopulation in the next generation? 4b. If migration was acting in here without selection, what would the frequency of ΔK be in the agricultural population in the next generation? 4c. If the natural forest population was substantially larger than the agricultural population, how might…
