In cucumbers, dull fruit (D) is dominant over glossy (d) fruit, orange friut (R) is dominant over cream fruit (r), and bitter co
tyledon (B) is dominant over non-bitter cotyledons (b). The three characters are encoded by genes located on different pairs of chromosomes. A plant homozygous for dull, orange fruit and bitter cotyledons is crossed with a plant that is homozygous for glossy, cream fruit and non-bitter cotyledons. The F1 are intercrossed to produce the F2. Assume that all 3 traits are encoded by independent genes.
a. Write out the parental anf F1 crosses using appropriate genotypic annotation. Indicate the phenotypes and their expected proportions in the F1 and F2.
b. An F1 plant is crossed with a plant that has glossy, cream fruit and non-bitter cotyledons. Write out this cross using appropriate annotation, and give the genotypes, phenotypes, and respectuve proprtions among the progeny of this cross.
