- Height in humans is controlled by the additive action of genes and the action of environmental factors. For the purposes of this problem, assume that height is controlled by four genesA, B, C, and Dand that there are no environmental effects. Assume further that additive alleles contribute two units of height and partially additive alleles contribute one unit of height. a. Given these assumptions, can two individuals of moderate height produce offspring that are much taller and shorter than either parent? If so, how can this happen? b. Can someone of minimum height and someone of intermediate height have children taller than the parent of intermediate height? Why or why not?Figure 19-11 shows the expected distributions for thethree genotypic classes if the B locus is a QTL affectingthe trait value.a. As drawn, what is the dominance/additive (D/A)ratio?b. How would you redraw this figure if the B locus hadno effect on the trait value?c. How would the positions along the x-axis of thecurves for the different genotypic classes of the B locuschange if D/A = 1.0?The heritability for egg weight in a group of chickens on a farm inMaine is 0.95. Are the following statements regarding this heritabilitytrue or false? If a statement is false, explain why.A. The environment in Maine has very little effect on the outcomeof this trait.B. Nearly all of the phenotypic variance for this trait in this groupof chickens is due to genetic variance.C. The trait is polygenic and likely to involve a large number ofgenes.D. Based on the observation of the heritability in the Mainechickens, it is reasonable to conclude that the heritability foregg weight in a group of chickens on a farm in Montana isalso very high.
- A bean breeder is working with a population in which themean number of pods per plant is 50 and the variance is10 pods2. The broad-sense heritability is known to be 0.8.Given this information, can the breeder be assured thatthe population will respond to selection for an increase inthe number of pods per plant in the next generation?The Turner Kieser Syndrome (or nail patella syndrome) is a dominant human disease (prevalence about 1/100.000), which impairs the normal development of, nails and kneecaps (patella). In the following study the mutant allele for this gene is noted "M" and the wild type allele "m". On the family tree below black symbols (circles for women and squares for men) indicate people suffering from KSS and open symbols represent healthy persons.

Complete the table by calculating the variances and coefficient of variation for each population and answer the questionswhich follow (See image) 1. Explain the possible reasons for the observed differences in the sample means. Account forthe differences in the sample means of P1 and P2. Similarly, account for the differences in thesample means of the F1 and F2. Compare the difference in the parental generations with thatin the filial generations.2. Interpret the CV values from each population.3. Compare the sample variances of P1 and P2. Account for any differences. Similarly, comparethe sample variances of the F1 and F2 generations, and account for any differences. Give thepossible causes of variation in each generation.4. Calculate the broad-sense heritability of plant height in this species. Interpret your results.
- Tomato plants with the same genotype grown in a nearly uniform environment like a greenhouse will probably show broad sense heritability for fruit size than the same plants grown in a more heterogeneous environment such as in an outdoor field. O higher O lower the same (because heritability is a fixed attribute of a given trait) Incorrect Broad sense heritability is the proportion of total phenotypic variance due to genetic factors (as opposed to environmental factors). Do you think this will be the same under all environmental conditions? X XThe following table gives the percentage of twinpairs studied in which both twins expressed the same phenotypefor a trait (concordance). Percentages listed arefor concordance for each trait in monozygotic (MZ) anddizygotic (DZ) twins. Assuming that both twins in eachpair were raised together in the same environment, whatdo you conclude about the relative importance of geneticversus environmental factors for each trait?Corn and Mendelian Genetics Red Smooth Red Wrinkled Yellow smooth yellowwrinkled #Expected 25 25 25 25 #observed 29.6 53.4 7.2 9.8 X2 value 0.85 32.26 12.67 9.24 The data above is from genetic tracking two traits inherited in Corn.

- In domesticated dogs, size has a high heritability, andthe trait is determined by only a small number ofgenes. In contrast, genetic variation at more than180 QTLs explains only a very small proportion ofthe high heritability for height in humans. What couldexplain the missing heritability in humans, and howcould you test your hypothesized explanations?Two different varieties of potato plants produce potatoes with thesame mean weight of 1.5 pounds. One variety has a very low variancefor potato wieght, and the other has a much higher variance. A. Discuss the possible reasons for the differences in variance.B. If you were a potato farmer, would you rather raise a varietywith a low or high variance? Explain your answer from apracticalpoint of view.C. If you were a potato breeder and you wanted to develop potatoeswith a heavier weight, would you choose the variety witha low or high variance? Explain your answer.. A chicken breeder is working with a population in whichthe mean number of eggs laid per hen in one month is 28and the variance is 5 eggs2. The narrow-sense heritabilityis known to be 0.8. Given this information, can the breeder expect that the population will respond to selectionfor an increase in the number of eggs per hen in the nextgeneration?a. No, applying selection is always risky and a breedernever knows what to expect.b. No, a breeder needs to know the broad-senseheritability to know what to expect.c. Yes, since the narrow-sense heritability is close to1 (0.8), then we would expect selective breeding couldlead to increased egg production in the next generation.d. Yes, since the variance is greater than 0.e. Both c and d are correct.
