The phenotype and ratio of a cross between green colored flowers of a plant. Introduction: Phenotype refers to the observable traits of organisms, while genotype signifies genetic-makeup or arrangement of genes and alleles of the organism. The phenotype depends on the genotype. The interaction between alleles can be observed as incomplete dominance, which can give rise to three phenotypes even when the phenotype is controlled by only two forms of a gene. In a particular plant species, two alleles control flower color, which can be yellow, green, or blue. Crosses of these plants produce the following offsprings: Parental phenotypes Offspring phenotypes ratio Yellow × yellow All yellow Green × yellow Green or yellow (1:1) Green × blue Blue or green (1:1) Blue × blue All blue

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.

In some plants, a true-breeding, red-flowered variety gives all pink flowers when crossed with a white-flowered strain: RR (red) X rr (white) = Rr (pink). Flower position in this plant may either be axial (dominant) or terminal (recessive). What will be the phenotypic ratios of the F1 generation resulting from the following cross: axial-red (true-breeding) X terminal-white? What will the phenotypic ratios of the F2 be? SHOW ALL WORK

In sesame plants, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant to wrinkled leaf (l). Pod type and leaf type are inherited independently. Determine the genotypes for the two parents for all possible matings producing the following offspring: 318 one-pod, normal leaf and 98 one-pod, wrinkled leaf. show your solution using punnet square
