- In a cross between a black and a white cat, all members of the Fi generation are black. The F2 generation is made up of approximately 3/4 black and 1/4 white cat. (i) Diagram this cross, showing the genotypes and phenotypes of the parents, F, and F2 generations.

- In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow: 3/16 blue: 3/16 red: 1/16 mauve In still another cross using true-breeding parents, yellow-flowered plants are crossed with mauve-flowered plants. Again, all F1 plants had yellow flowers and the F2 showed a 9:3:3:1 ratio, as just shown. (a) Describe the inheritance of flower color by defining gene symbols and designating which genotypes give rise to each of the four phenotypes. (b) Determine the F1 and F2 results of a cross between truebreeding red and true-breeding mauve-flowered plants.arrow_forwardIn snapdragons, red flower color (R) is incompletely dominant over white flower color (r), so that the heterozygote has pink flowers. A red snapdragon is crossed with a white snapdragon, and the F1 are intercrossed to produce F2. What is the genotype and phenotypes of the F1 and F2, along with their expected proportions? If the F1 are backcrossed to the white parent, what will be the expected genotype and phenotype of the offspring? If the F1 are backcrossed to the red parent and the resulting progeny are intercrossed, what is the expected proportions of genotypes and phenotypes in the progeny?arrow_forwardThe 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_forward
- In venetian violets, three phenotypes occur with respect to flower color: a deep violet (almost back), a white, and a pale lavender. Two pale lavender flowered plants have been crossed. The F1 from this cross has individuals with deep violet flowers, with pale lavender flowers, and individuals with white flowers. A. what are the parent genotypes? B. what would the expected phenotypic ratio be in these F1 plants?arrow_forwardIn watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1 are intercrossed to produce the F2. What will be the phenotypic ratios in the F2? 2. If an F1 plant is backcrossed with the bitter, yellow-spotted parent, what phenotypes and proportions are expected in the offspring? 3. If an F1 plant is backcrossed with the sweet, non-spotted parent, what phenotypes and proportions are expected in the offspring? 4. In cats, curled ears (Cu) result from an allele that is dominant over an allele for normal ears (cu). Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears.
