Chapter 9, Problem 4PDQ
A plant may have green, white, or green-and-white (variegated) leaves on its branches, owing to a mutation in the chloroplast that prevents color from developing. Predict the results of the following crosses:

List the possible genotypes of the parents if a cross resulted in a F1-generation consisting of 50% white colonies and 50% red colonies:
In corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of corn plants (i.e. the tassel) unable to produce fertile pollen; the female parts, however, remain receptive to pollination by pollen from male-fertile corn plants. However, the presence of a nuclear fertility restorer gene F restores fertility to male-sterile lines.
Using the following color-coded circles, simulate the crosses indicated below. Put the illustrations of crosses in the spaces provided. Be sure to include in the labels the genotypes and phenotypes of the offspring in each cross.
Big light green circle - male-sterile cytoplasm
Big orange circle - male-fertile cytoplasm
Small orange circle - FF nucleus
Small half-light green-half-orange circle - Ff nucleus
Small light-green circle - ff nucleus
In sweet peas, gene C or P alone produces white flowers, the purple colour being due to the presence of both these factors. What will be the flower colour of the offsprings of the following crosses, in which genotypes of parents are given;a) A white flowered plant crossed with a purple produces offspring, of which three-eighth are purple and five-eighth white.

- Identify how many genes are associated with the types of crosses: A.) Monohybrid B.) Dihybridarrow_forwardA wheat plant that is light green in color is found growing in a field. Biochemical analysis reveals that chloroplasts in this plant produce only 50% of the chlorophyll normally found in wheat chloroplasts. Propose a set of crosses to determine whether the light-green phenotype is caused by a mutation in a nuclear gene or in a chloroplast gene.arrow_forwardThere are some members of the genus Datura that are trisomic for the chromosome set, which carries the genes for purple (p+) and white (p) flower color. In a cross involving a trisomic p+ p+ p female and pollen from a normal p+ p plant, what is the expected proportion of purple and white flowered individuals?arrow_forward

(Do your own representation, all characteristics first mentioned are dominant) Tall x dwarf Hairy x glabrous Red x white Smooth x wrinkled Yellow x greenarrow_forwardConsider this cross in pea plants: Tt Rr yy Aa × Tt rr Yy Aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the expected phenotypic outcomeof this cross? Have one group of students solve this problem bymaking one big Punnett square, and have another group solve it bymaking four single-gene Punnett squares and using the multiplication method. Time each other to see who gets done first.arrow_forwardGiven the following information, determine the inheritance of flower color in this plant and determine the genotypes of the parental individuals, which are from pure- breeding lines.

Green squash happens to be very popular with your customers and can be sold at a higher price than white or yellow squash. Which of the following squash plant crosses will give you a higher number of green squash to bring to the market? Show your work 1. AaBb (white) x Aabb (yellow) or 2. aaBb (white) x Aabb (yellow) b) What type of epistasis does this squash coloration likely demonstrate and why?arrow_forwardCross 1: Purple Stem (P1) x Brown Stem (P2) = F1 Generation (all purple stem plants). Cross 2: F1 x F1 = F2 Generation (295 purple stem plants and 102 brown stem plants). a) What is the phenotype ratio of the F2 generation? b) What is the geneotype ratio of the F2 generation? c) Which trait is dominant?arrow_forward
