- In Figure 1-6, the students have 1 of 15 different heights,plus there are two height classes (4′11″ and 5′ 0″) forwhich there are no observed students. That is a total of17 height classes. If a single Mendelian gene can account for only two classes of a trait (such as purple orwhite flowers), how many Mendelian genes would beminimally required to explain the observation of 17height classes?. Tay-Sachs disease is a rare human disease in which toxic substances accumulate in nerve cells. The recessiveallele responsible for the disease is inherited in a simpleMendelian manner. For unknown reasons, the allele ismore common in populations of Ashkenazi Jews ofeastern Europe. A woman is planning to marry her firstcousin, but the couple discovers that their sharedgrandfather’s sister died in infancy of Tay-Sachsdisease.a. Draw the relevant parts of the pedigree, and showall the genotypes as completely as possible.b. What is the probability that the cousins’ first childwill have Tay-Sachs disease, assuming that all peoplewho marry into the family are homozygous normal?For all seven characters described in the data of Mendel allowed the F2 plants to self-fertilize. He found that whenF2 plants with recessive traits were crossed to each other, theyalways bred true. However, when F2 plants with dominant traitswere crossed, some bred true but others did not. A summary ofMendel’s results is shown to the right When considering the data in this table, keep in mind that theydescribe the characteristics of the F2 generation parents that haddisplayed a dominant phenotype. These data were deduced byanalyzing the outcome of the F3 generation. Based on Mendel’slaws, explain why the ratios were approximately 1:2
- Mendel studied a tall variety of pea plants with stemsthat are 20 cm long and a dwarf variety with stems thatare only 12 cm long.a. Under blending theory, how long would you expectthe stems of first and second hybrids to be?b. Under Mendelian rules and assuming stem lengthis controlled by a single gene, what would you expectto observe in the second-generation hybrids if all thefirst-generation hybrids were tall?The accompanying pedigree shows a very unusual inheritance pattern that actually did exist. All progeny areshown, but the fathers in each mating have been omittedto draw attention to the remarkable pattern.a. Concisely state exactly what is unusual about thispedigree.b. Can the pattern be explained by Mendelianinheritance?In Mendel’s 1866 publication as shown in Figure 1-4,he reports 705 purple-flowered (violet) offspring and224 white-flowered offspring. The ratio he obtained is3.15:1 for purple: white. How do you think he explainedthe fact that the ratio is not exactly 3:1?
- Both members of a couple know that they are carriers of the cysticfibrosis allele. None of their three children has cystic fibrosis, but anyone of them might be a carrier. The couple would like to have a fourthchild but are worried that he or she would very likely have the disease,since the first three do not. What would you tell the couple? Would itremove some uncertainty from their prediction if they could find outwhether the three children are carriers?Describe the characteristics of the garden pea thatmade it a good organism for Mendel’s analysis of thebasic principles of inheritance. Evaluate how easy ordifficult it would be to make a similar study of inheritance in humans by considering the same attributesyou described for the pea.This problem examines possible biochemical explanations for variations of Mendel’s 9:3:3:1 ratio. Exceptwhere indicated, compounds 1, 2, 3, and 4 have different colors, as do mixtures of these compounds. Aand B are enzymes that catalyze the indicated steps ofthe pathway. Alleles A and B specify functional enzymes A and B, respectively; these are completelydominant to alleles a and b, which do not specify anyof the corresponding enzyme. If functional enzyme ispresent, assume that the compound to the left of thearrow is converted completely to the compound to theright of the arrow.

- Labrador retrievers may be black, brown, or golden in color (seethe chapter opening photograph on p. 53). Although each colormay breed true, many different outcomes occur if numerous littersare examined from a variety of matings, where the parentsare not necessarily true-breeding. The following results showsome of the possibilities. Propose a mode of inheritance that isconsistent with these data, and indicate the corresponding genotypesof the parents in each mating. Indicate as well the genotypesof dogs that breed true for each color.(a) black * brown ¡ all black(b) black * brown ¡ 1/2 black1/2 brown(c) black * brown ¡ 3/4 black1/4 golden(d) black * golden ¡ all black(e) black * golden ¡ 4/8 golden3/8 black1/8 brown(f) black * golden ¡ 2/4 golden1/4 black1/4 brown(g) brown * brown ¡ 3/4 brown1/4 golden(h) black * black ¡ 9/16 black4/16 golden3/16 brownFrom the pedigree in Figure 3-25, what principle can youdeduce about the inheritance of mitochondrial diseasefrom affected fathers?. Considering the yellow and green pea color phenotypes studied by Gregor Mendel:a. What is the biochemical function of the proteinthat is specified by the gene responsible for thepea color phenotype?b. A null allele of a gene is an allele that does notspecify any of the biochemical function that thegene normally provides. Of the two alleles Y and y,which is more likely to be a null allele?c. In terms of the underlying biochemistry, why is theY allele dominant to the y allele?d. Why are peas that are yy homozygotes green?e. The amount of the protein specified by a gene isroughly proportional to the number of functionalcopies of the gene carried by a cell or individual.What do the phenotypes of YY homozygotes, Yyheterozygotes, and yy homozygotes tell us aboutthe amount of the Sgr enzyme (the product of thepea color gene) needed to produce a yellow color?
