Different populations of Dr. Remington's rock cress plants (Arabidopsis lyrata) are pure-breeding for different combinations of hairy vs. smooth leaves (alleles H vs. h at one gene), and lobed vs. non-lobed leaves (alleles L vs. I at a second gene linked to the first). He has a tray of F₁ plants with hairy lobed leaves (genotype Hh Ll), but lost the label so he doesn't know which populations were crossed to produce them. He does a testcross of the F₁ plants, and obtains the following progeny: 81 hairy lobed, 18 hairy non-lobed, 24 smooth lobed, and 77 smooth non- lobed. What alleles were on each of the two homologous chromosomes in the F₁ plants, and what were the phenotypes of the two parent populations of the F₁ plants?

The text outlines some of the problems Frederick William I encountered in his attempt to breed tall Potsdam Guards. a. Why were the results he obtained so different from those obtained by Mendel with short and tall pea plants? b. Why were most of the children shorter than their tall parents?
A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
. In corn, the allele A allows the deposition ofanthocyanin (blue) pigment in the kernels(seeds), while aa plants have yellow kernels.At a second gene, W- produces smoothkernels, while ww kernels are wrinkled. Aplant with blue smooth kernels was crossedto a plant with yellow wrinkled kernels. Theprogeny consisted of 1447 blue smooth, 169blue wrinkled, 186 yellow smooth, and 1510yellow wrinkled.a. Are the a and w loci linked? If so, how farapart are they?b. What was the genotype of the blue smoothparent? Include the chromosomearrangement of alleles.c. If a plant grown from a blue wrinkled progenyseed is crossed to a plant grown from ayellow smooth F1 seed, what kinds of kernelswould be expected, and in what proportions?
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?
In a dihybrid cross of two bi-allelic Mendelian genes, A (two alleles – completely dominant A and recessive a), and B (two alleles – completely dominant B and recessive b), such that the parental generation comprises of pure-bred homozygotes (i.e. AABB with aabb), what are the expected genotype and phenotype ratios in the F1 and F2, if the F1 cross is (a) an intercross and if the F1 cross is (b) a testcross

. 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…
From a presumed testcross of 2 plants of genotype Aa x aa (in which A represents red and a represents white petals on a plant) we get 5000 red petal plants, and 5400 white petals plants. Using the Chi-squared test, what chi-squared value do we get for this?
In one study, Gregor Mendel crossed yellow-seeded, tall garden pea with a green-seeded,short garden pea. The F1 offspring were all yellow-seeded and tall. Assumingindependent assortment of these two genes, what phenotypes and proportions did he finamong F2 offspring when the F1 garden peas are allowed to fertilize themselves? Show the solution with punnett square.
Three genes in fruit flies affect a particular trait, andone dominant allele of each gene is necessary to get awild-type phenotype.a. What phenotypic ratios would you predict amongthe progeny if you crossed triply heterozygous flies?b. You cross a particular wild-type male in successionwith three tester strains. In the cross with one testerstrain (AA bb cc), only 1/4 of the progeny are wildtype. In the crosses involving the other two testerstrains (aa BB cc and aa bb CC), half of the progeny are wild type. What is the genotype of thewild-type male?
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
