8) Suppose that red flower color (R-) is dominant to white flower color (rr) in Petunia. A friend has a petunia plant with red flowers and wants to determine whether the plant is RR or Rr. In order to determine the genotype, you cross it with a white-flowered petunia. (i) What is the name of the cross that you performed? (ii) How will this cross help you determine the genotype of the red flowered petunia? That is, how will the results from this cross differ if the red-flowered petunia is RR vs Rr?

Tallness (T ) in snapdragons is dominant to dwarfism (t ), while red (R ) flower color is incompletely dominant to white (R' ). The heterozygous condition results in pink (RR' ) flower color. The genes for these traits occur on separate chromosomes. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white fowers. a) Determine the genotypes of the parents. b) Determine all the types of gametes each parent can produce. c) Complete the Punnett...

In the datura plant, purple flower color is controlled by a dominant allele P. White flowers are found in plants homozygous for the recessive allele p. A heterozygous purple-flowered plant is self-fertilized by its own pollen and produces five seeds. a) Probability than any one seed will grow into a white-flowered plant? b) Probability that at least two of the five seeds will grow into white-flowered plants?

In snapdragons, the plant height gene and the flower color genes are located on different chromosomes. Tall (T) is dominant to dwarf (t). Red flowers (FR) are incompletely dominant to white (FW), with the hybrid being pink. A homozygous tall-white is crossed to a homozygous dwarf-red,. The F1 plants are then self-fertilized to produce an F2 generation. a. What is the genotype and phenotype of the F1? b. What proportion of the F2 will have pink flowers? c. What proportion...

You are studying inheritance of various characters in marigolds including flower color (purple or blue), seed color (white or brown) and seed shape (round or oblong). When you cross a plant that is true breeding for blue flowers, white and oblong seeds with a plant that is true breeding for purple flowers, brown and round seeds you find that all of the offspring have blue flowers, and round, white seeds. You then cross these F1 plants with each other and...

In snapdragons, two genes control flower color, which can be red, pink, or white. Gene A encodes an enzyme that makes a precursor to red pigment, and gene R encodes the enzyme that makes the red pigment from the precursor. This makes Gene A epistatic to Gene R (if there is no precursor made, there can be no red pigment). Allele A (pigmented) is completely dominant to a (no pigment, white), and R isincompletely dominant to r. What would be...
