Following up on Question 6, which of the following statements is correct? A.The is an example of frequency-dependent selection. B.The H1 allele is deleterious and will eventually be selected against in the population, resulting in its extinction. C.The H2 allele is deleterious and will eventually be selected against in the population, resulting in its extinction. D.In this example, whether dominant or recessive, it does not affect an allele’s fitness. E.None of the above Minotaur is only found in the Labyrinth on the island of Crete. The area is famous for its annualspectacle of "Minotaur run," where herds of Minotaur rush out of the Labyrinth to reach theirbreeding grounds on the beautiful Aegean seashore. A group of Olympianscientists discovered that the horn size of the Minotaur is controlled by asingle locus H. A previous population genetic survey showed that there areonly two allele in this locus, H1 and H2. Furthermore, it was found that theH2 allele is recessive. Several studies showed that the long-hornedindividuals (H,H1 and HH2) tend to be tangled up along the way duringthe annual migration out of the Labyrinth, such that only 80% of the long-horned individuals can make it out of the Labyrinth alive. Once outside theLabyrinth, the short-horned individuals tend to be less successful at findingfood, thus 60% would die from starvation before the beginning of the breedingseason. Initially, the annual migration of Minotaur started out with 1,000 individuals (150 H,H1,500 H¡H2, and 350 H2H2) inside the Labyrinth.99

Color blindness in humans is caused by an X-linked recessive allele. Ten percent of the males of a large andrandomly mating population are color-blind. A representative group of 1000 people from this population migrates to a South Pacific island, where there are already1000 inhabitants and where 30 percent of the males arecolor-blind. Assuming that Hardy–Weinberg equilibrium applies throughout (in the two original populationsbefore the migration and in the mixed population immediately after the migration), what fraction of malesand females can be expected to be color-blind in the generation immediately after the arrival of the migrants?
You conduct an RFLP analysis of head weight in one strain of cabbage;you determine that seven QTLs affect this trait. In anotherstrain of cabbage, you find that only four QTLs affect this trait.Note that both strains of cabbage are from the same species, althoughthey may have been subjected to different degrees of inbreeding.Explain how one strain can have seven QTLs andanother strain four QTLs for exactly the same trait. Is the secondstrain missing three genes?
Half of the worlds population eats rice at least twice a day. Much of this rice is grown in flooded conditions, and different strains of rice are tolerant (survive) or intolerant (die) under these conditions. Rice breeders used genetic crosses to test whether tolerance to flooding is a dominant trait. Researchers used three true-breeding flood-tolerant strains, FR143, BKNFR, and Kurk, and two true-breeding flood- intolerant strains, IR42 and NB, in the crosses. Results were obtained from three sets of crosses and are reported in the Table below: Results of cross of F1 to tolerant parent: F1 plants were crossed with the tolerant parent of the cross. Number of Plants Progeny Analyzed from Intolerant Tolerant Cross Alive Dead Total 1. F2 results of cross: IR42 FR13A 187 77 264 IR42 BKNFR 192 73 265 NB Kurk 142 52 195 2.

Justify your conclusion by explaining the results from each of the three sets of crosses in terms of genotypes and phenotypic ratios. Source: T. Setter et al. 1997.

How Can We Measure Allele Frequencies in Populations? Drawing on your newly acquired understanding of the HardyWeinberg equilibrium law, point out why the following statement is erroneous: Because most of the people in Sweden have blond hair and blue eyes, the genes for blond hair and blue eyes must be dominant in that population.
Different species of crickets have distinct songs, andthey use these songs for mate recognition. Researcherscrossed two species of Hawaiian crickets (Laupala paranigra and L. kohalensis) whose songs are distinguishedby pulse rate (the number of pulses per second; Shaw etal., Molecular Ecology 16, 2007, 2879–2892.) Then, theymapped QTL in the F2 population derived from thiscross. Six autosomal QTL were detected. The mean traitvalues (pulses per second) at the three genotypic classesin the F2 for each QTL are shown in the table below,where P indicates the L. paranigra allele and K indicatesthe L. kohalensis allele.a. Calculate the additive (A) and dominance (D) effectsand the D/A ratio for each of the six QTL.b. Which of these QTL shows the greatest amount ofdominance?c. Which of these has the largest additive effect?d. The mean pulse rate for L. kohalensis is 3.72, and it is0.71 for L. paranigra. Do all six QTL act in the expecteddirection with the L. kohalensis allele conferring a…
The gamma globulin of human blood serum exists in two forms, Gm(a+) and Gm(a-), specified respectively by an autosomal dominant gene Gm(a+) and its recessive allele Gm(a-). Broman et al. (1963) recorded the tabulated phenotypic frequencies in three Swedish populations. Assuming the populations were at Hardy-Weinberg equilibrium, calculate the frequency of heterozygotes in each population.
A botanist studying water lilies in an isolated pond observedthree leaf shapes in the population: round, arrowhead, and scalloped.Marker analysis of DNA from 125 individuals showed theround-leaf plants to be homozygous for allele r1, while the plantswith arrowhead leaves were homozygous for a different allele atthe same locus, r2. Plants with scalloped leaves showed DNA profileswith both the r1 and r2 alleles. Frequency of the r1 allele wasestimated at 0.81. If the botanist counted 20 plants with scallopedleaves in the pond, what is the inbreeding coefficient F forthis population?
The human MN blood type is determined by two codominant alleles, LMand LN. The frequency of LM in Eskimos on a small Arctic island is0.80.a. If random mating takes place in this population, what are the expectedfrequencies of the M, MN, and N blood types on the island?b. If the inbreeding coefficient for this population is 0.05, what are theexpected frequencies of the M, MN, and N blood types on the island?
At the molecular level, explain why quantitative traits often exhibita continuum of phenotypes within a population. How does theenvironment help produce this continuum?
In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss). Question: The frequency of s (q) is equal to Question 1 options: 0.625 0.375 0.140 0.280
