In a species of the cat family, eye color can be gray, blue, green, or brown, and each trait is true breeding. In separate crosses involving homozygous parents, the following data were obtained:Cross P₁ F₁ F₂A green x gray all green 3/4 green: 1/4 grayB green x brown all green 3/4 green: 1/4 brownC. gray x brown. all green 9/16 green: 3/16 brown3/16 gray: 1/16 blueIn a cross between a gray-eyed cat and one of unknown genotype and phenotype, the F₁ generation was not observed. However, the F₂ resulted in the same F₂ ratio as in cross C. Determine the genotypes and phenotypes of the unknown P₁ and F₁ cats.

How many genes are involved? Define gene symbols and indicate which genotypes yield each phenotype.

In a plant, a tall variety was crossed with a dwarf variety. All F₁ plants were tall. When F₁xF₁ plants were interbred, 9/16 of the F₂ were tall and 7/16 were dwarf.What proportion of the F₂ plants will be true breeding if self-fertilized? List these genotypes.

In a plant, a tall variety was crossed with a dwarf variety. All F₁ plants were tall. When F₁xF₁ plants were interbred, 9/16 of the F₂ were tall and 7/16 were dwarf.Explain the inheritance of height by indicating the number of gene pairs involved and by designating which genotypes yield tall and which yield dwarf. (Use dashes where appropriate.)

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.Determine the F₁ and F₂ results of a cross between true-breeding red and true-breeding mauve-flowered plants.
