- 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?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?A dihybrid cross is performed between two heterozygous individuals (heterozygous for two traits). The resulting offspring had 62 individuals that were dominant for trait 1 and 2 (D/D), 7 individuals that were R/R, 21 individuals that were R/D, and 25 individuals that were D/R. Using Mendelian inheritance as the null hypothesis, use χ2 analysis to determine if the trait follows Mendelian inheritance. A. How many D/D phenotype offspring are expected? B. How many R/D phenotype offspring are expected? C. How many degrees of freedom are there? D. What is your calculated χ2 value? E. What is the critical value if using a probability of 0.05? F. Does the trait follow Mendelian inheritance?
- What could be the genotypic and phenotypic ratios for a typical mendelian trait showed in the picture?Let R = Red flowers and r = white flowers, and T = tall plants and t = short plants. If the uppercase letters represent Mendelian dominant alleles, what is the phenotype of a plant with the genotype rrTt? white flowers, tall pink flowers, tall red flowers, tall red flowers, short white flowers, shortIn 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?
- Which of the following probabilities is correct (according to Mendel's law of independent assortment) regarding a mating of an Ss RR individual to an individual who is Ss Rr? (A – indicates the second allele is either dominant or recessive. A) Homozygous recessive: 10% B) Heterozygous both alleles: 50% C) ss R– : 15.5% D) S– RR: 37.5%In one of his experiments, Mendel crossed homozygous yellow plants with homozygous green plants. The resulting F1 generation was allowed to self-fertilize. The F2 generation produced 930 yellow seeds and 305 green seeds. What are the genotypes of this F2 generation? O YY : yy O Yy : yy O Yy: yy O YY: Yy : yyWhen Mendel set up a Parental (P) cross between true breeding purple and white flowered plants to generate the F1 and then allowed the F1 to self-pollinate to generate the F2 he saw a dominant to recessive ratio of 3:1. What phenotypic ratio would be expected if he crossed the F1 with the original purple parent? a) 3:1 b) 9:3:3:1 c) 1:1 d) 4:0
- On the basis of Mendel’s observations (i.e. Mendelian patterns), predict the results from the following crosses with peas. Show the results in terms of genotypes, phenotypes, and their proportions in the offspring. The progeny of a tall (dominant and homozygous) variety crossed with a dwarf variety. The progeny of (a) self-fertilized. The progeny from (a) crossed with the original tall parent. The progeny of (a) crossed with the original dwarf parent.a) how many degree of freedom b) what is the chi square value c) what is the percentage assurance d) is your data a good fit for the ration you expected. Previous question asks in pea plants stem length is either long dominant or short recessive. 2 heterozygous long pea plants were crossed. The progeny included 402 pea plants, 308 of which were long and 94 of which were short. The ratio is 3:1This 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.)
