Chapter 2, Problem 24P
The self-fertilization of an pea plant produced from a parent plant homozygous for yellow and wrinkled seeds and a parent homozygous for green and round seeds resulted in a pod containing seven peas. (Yellow and round are dominant.) What is the probability that all seven peas in the pod are yellow and round?

The self-fertilization of an F1 pea plant produced froma parent plant homozygous for yellow and wrinkledseeds and a parent homozygous for green and roundseeds resulted in a pod containing seven F2 peas. (Yellow and round are dominant.) What is the probability that all seven peas in the pod are yellow and round?
A pea plant that is heterozygous with regard to seed color (yellowis dominant to green) is allowed to self-fertilize. What are the predicted outcomes of genotypes and phenotypes of the offspring?
Heterozygous round, homozygous green seeded plants were mated with heterozygous yellow, homozygous wrinkled seeded plants. What is the probability of producing a pod of 7 peas with 3 round and green seeds, 2 round and yellow seed, and 2 wrinkled yellow seeds?

- A cross between a homozyous purple-flowedr and a homozygous white flowerd pea plants, results in offsprings with purple flowers. Does this demonstrate complete or incomplete dominance?arrow_forwardIn flowers, purple flower color is dominant and denoted by "P" while white flower color is recessive and is denoted by "p". In a monohybrid cross between 2 heterozygous purple flowers, what is the expected phenotypic offspring ratio?arrow_forwardA tall pea plant with axial flowers was crossed to a dwarf plantwith terminal flowers. Tallness and axial flowers are dominanttraits. The following offspring were obtained: 27 tall, axial flowers;23 tall, terminal flowers; 28 dwarf, axial flowers; and 25 dwarf,terminal flowers. What are the genotypes of the parents?arrow_forward
- What are the possible phenotypes of the offspring of a short (recessive) pea plant with axial flowers (dominant heterozygous) and a tall pea plant (heterozygous) with terminal flowers. If 100 pea plants are produced, how many would have each of the possible phenotypes?arrow_forwardTwo pink-flowered four-o’clock plants were crossed to each other.What is the probability that a group of six offspring from this cross willbe composed of one pink-, two white-, and three red-flowered plants?arrow_forwardIn Pea plants, Round (Smooth) seed coat is dominant over wrinkled seed coat. When two heterozygous plants are crossed, what percentage of plants would have Round seeds? Wrinkled seeds?arrow_forward
- Radishes may be round, oval and lomg. Aside from this, they may be red, purple or white in color. Red x white produces progeny, all of which are purple. If purple oval will be crossed with purple oval, how many types of phenotypes will appear? If purple oval are crossed with white, long radishes, then what genotypic and phenotypic ratios exist in the progeny? Indicate the phenotypes of the offspring.arrow_forwardIf an incompletely dominant red-flowered plant is crossed with an incompletely dominant white-flowered plant, what are the genotypes and phenotypes of the plant F1 generation? What genotypes and phenotypes will be produced in the F2 generation?arrow_forwardIn peas, round seeds are dominated to wrinkled seeds. A heterozygous round seeded plant is crossed with a wrinkled seeded plant. What are the genotypic and phenotypic ratios of the F1 generation? Show your Punnett square. What percentage of their offspring can be expected to have round seeds?arrow_forward
- The crossing of two orange-flowering plants results in ~2/3 orange-flower progeny and ~1/3 white-flower progeny. The crossing of two orange-flowering F1 plants generates the same progeny ratios as observed for the parental cross, while the crossing of white-flowering F1 plants only produces white-flowering progeny. What is a likely explanation for these results?arrow_forwardIn certain plants, tall (T) is dominant to short (t). If a heterozygous plant is crossed with a homozygous short plant, what is the probability that the offspring will be short? Show the punnett square please.arrow_forwardMany of the color varieties of summer squash are determined by two different interacting genes A and B: AA or Aa gives white colored squash, aaBB or aaBb gives yellow squash, and aabb produces green squash. A plant producing white squash is self-crossed. Three fourths of the offspring produces white squash; one fourth produces green squash. What is the genotype of the parent plant producing white squash?arrow_forward
