Textbook Question
Chapter 13, Problem 2S
Assume that the genes for seed color and seed shape are located on the same chromosome. A plant heterozygous for both genes testcrossed wrinkled green with the following results:
green, wrinkled 645
green, round 36
yellow, wrinkled 29
yellow, round 590
What were the genotypes of the parents, and how far apart are these genes?

- A cross is carried out between two pure lines of tomato plants, one having regular leaves and red fruit and the other having potato leaves and yellow fruit. The F1 generation all have regular leaves and red fruit. The F1 individuals are then crossed with one another. Question text The expected phenotypic ratio for leaf shape and fruit colour genes is 9:3:3:1, if both genes are on different chromosomes and assort independently during gamete formation. The information below represents two sets of data collected from the above cross. Data Set 1 is from a population of 5000 tomato plants and Data Set 2 is from a population of 50 tomato plants. Phenotypes Observed Probabilities Data Set 1(N = 5000) Data Set 2(N = 50) Regular Red 0.58 0.050 Regular Yellow 0.16 0.29 Potato Red 0.20 0.050 Potato Yellow 0.060 0.61 A.

Determine the genotypes of the parents, using the letter R.arrow_forwardIn corn, a pair of genes determines leaf shape and another pair determines pollen shape. A ragged-leafed plant with round-pollen was crossed to a ragged-leaf plant with angular pollen, and the resultant progeny were classified as follows: 186 ragged-leaf round-pollen 174 ragged-leaf angular pollen 57 smooth-leaf round pollen 63 smooth-leaf angular-pollen provide your hypothesis of the genotypes for the two parents. According to your hypothesis, what numbers would you have expected for each of the four classes of progeny? Follow the format of the number with the phenotypes in the question above. Test your hypothesis statistically using the chi-square method and indicate whether you accept or reject your hypothesis. Show your solutions.arrow_forwardImagine that the genes for seed color and seed shape are located on the same chromosome. A cross is made between two true-breeding plants. One plant produces green wrinkled seed (rryy) and the second parent produced round yellow seeds (RRYY).

- Renner carried out reciprocal crosses between two types of the evening primrose, Oenothera hookeri and O. muricata, known to have the same chromosome constitution. When the seed parent was O. hookeri, the plastids of the progeny were yellow; but when the seed parent was O. muricata, the plastids of the progeny were green. How might this difference in the results of reciprocal crosses be explained?arrow_forwardIn 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?

Also, double check your answer before posting. thank youarrow_forwardA plant bearing round seed coats is testcrossed, and half of the offspring bear round seed coats.

- Consider three yellow, round peas, labeled A, B, and C. Each was grown into a plant and crossed to a plant grown from a green, wrinkled pea.
