- 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?Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seedsshown are the F2 results of two Mendel's monohybrid crosses. Mendel crossed 2 heterozygote parents. If he were to expect segregation to happen normally, do the results match his expectations? state a null hypothesis that you will test using chi-square analysis. Calculate the chi-square value and determine the p value for both crosses a. Full pods: 882; constricted pods: 299 (full pods are dominant over constricted) b. violet flowers: 705; white flowers: 500 (violet dominant over white)
- O e. 1/8 QUESTION 3 In Mendel's pea plants, round shape (R) is dominant to wrinkled shape (r), and yellow color (Y) is dominant to green color (y). The alleles for seed shape and seed color sort independently. In the parental generation, Mendel crossed a true-breeding round, yellow-seeded plant with a true-breeding wrinkled, green-seeded plant to create an F1 generation. He then crossed the F1 offspring to eachother. What type of cross is this considered? O Dihybrid cross Heterozygous cross Testcross Genetic cross O Monohybrid cross QUESTION 4 - Save and Submit to save and submit.

I am having trouble on how to exactly get this. Please help.
- To assess Mendel’s law of segregation using tomatoes, a true-breeding tall variety (SS) is crossed with a true-breeding short variety (ss). The heterozygous F1 tall plants (Ss) were crossed to produce two sets of F2 data as follows. Set 1 Set 2 30 tall 300 tall 5 short 50 short Using the chi-square test, analyze the results for both datasets. Calculate the chi-square values and estimate the p-values in both cases.

- This question deals with Mendelian Genetics. Read each part carefully before you answer it. In the following questions, assume green pea pods are dominant over yellow pea pods. a) If a pea plant that is Heterozygous for pod color is crossed with a pea plant with yellow pods, what do you expect to see in the offspring (the f1 generation)? Specifically, what genotypes, what phenotypes, and in what ratios? (Use G for the green pod gene and g for the yellow pod gene.) (It is usually helpful to write out all the possible genotypes and give the phenotype for each genotype before answering the specific question.)In Mendel’s 1866 publication as shown in Figure 1-4, he reports 705 purple-flowered (violet) offspring and 224 white-flowered offspring. The ratio he obtained is 3.15:1 for purple: white. How do you think he explained the fact that the ratio is not exactly 3:1?In a typical one trait experiment of Mendel's, yellow pureline peas (YY) are crossed with green pureline peas (yy). The offspring are yellow. Then, those offspring are selfed. Which statements are / would be true about this experiment?
