In Mendel's genetic experiments many characteristics of the plants were quantified, such as their height (tall or short), flower position (axial or terminal), and seed color (colored or white). Suppose 100 plants are measured, and 37 are tall with axial flowers and colored seeds. Further, suppose a total of 26 plants have white seeds, 4 of them being short and 7 having terminal flowers. There are no short plants with terminal flowers, and the total number of short plants is 12. What is the probability a randomly selected plant will have flowers in the terminal position? Round your answer to THREE DECIMAL places. Also, double check your answer before posting. thank you

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 seeds
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.
A cross was made between two pea plants, TtAa and Ttaa, whereT = tall, t = dwarf, A = axial, and a = terminal. What is the probability that the first three offspring will be tall with axial flowers or dwarf with terminal flowers and the fourth offspring will be tall with axial flowers? Discuss what operation(s) (e.g., product rule or binomial expansion equation) you used and in what order they were used
The trait for medium-sized leaves in iris is determined by the genetic condition PP'. Plants with large leaves are PP, whereas plants with small leaves are P'P'. The trait for red flowers is controlled by the genes RR, pink by RR', and white by R'R'. A cross is made between two plants each with medium-sized leaves and pink flowers. If they produce 640 seedlings, what would be the expected phenotypes, and in what numbers would they be expected? View keyboard shortcuts EditViewInsertFormatToolsTable 12pt Paragraph
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 corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aaplants have yellow kernels. At a second gene, W–produces smooth kernels, while ww kernels are wrinkled. A plant with blue smooth kernels was crossedto a plant with yellow wrinkled kernels. The progenyconsisted of 1447 blue smooth, 169 blue wrinkled,186 yellow smooth, and 1510 yellow wrinkled.a. Are the a and w loci linked? If so, how far apartare they?b. What was the genotype of the blue smooth parent?Include the chromosome arrangement of alleles.c. If a plant grown from a blue wrinkled progeny seedis crossed to a plant grown from a yellow smoothF1 seed, what kinds of kernels would be expected,and in what proportions?
In a genetic cross between a homozygous tall plant with homozygous purple flowers and a homozygous short plant with heterozygous purple flowers, how many short plants will you expect in the F2 generation if you sample 36 individuals? Both tall and purple are dominant.
Imagine you are given two tall plants, but you do not know their genotype (see Figure 16-12). There are three possibilities—they might both be TT or both Tt or one TT and the other Tt. Imagine you cross the two plants, wait for them to produce seeds, and then plant the seeds. If all resulting plants are tall, can you then determine what the genotypes of the two parents are? If approximately half the resulting plants are tall and about half are short, can you then figure out the genotypes of the parents?
Mendel found that three traits in peas—height, flower color, and pod shape—are determined by different genes, and that these genes assort independently. Suppose that true-bred tall plants with violet flowers and inflated pods are crossed to true-bred dwarf plants with white flower and constricted pods. All the plants in the F1 generation are tall, with violet flowers and inflated pods. If these F1 plants are self-fertilized, what fraction of their offspring are expected to … a.)show all three dominant phenotypes? b.)be tall with white flowers and constricted pods?
In classical Mendelian genetics, how can one check the genotype of a parent (A) expressing the characters of a dominant allele? Select one: a. By performing a back cross with a recessive homozygote parent (B). If the A parent is homozygote for the dominant allele, then all the individuals from the F1 will display the dominant character. If the parent A was, instead, a heterozygote, then 50% of the F1 progeny will express the recessive character (homozygote recessive) and 50% the dominant one (heterozygotes). b. It is impossible to check such genotype without using specific molecular assays. c. By performing a back cross with a dominant homozygote parent (B). If the A parent is homozygote for the dominant allele, then all the individuals from the F1 will display the dominant character.
