Detailed explanation-1: -The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. This situation occurs due to the blending of both the alleles.

Detailed explanation-2: -When a red flowered plant is crossed with a white flowered plant, ideally the offsprings should bear either red and white flower. However, in the case where the trait flower color exhibits incomplete dominance, all the offsprings will give forth pink colored flowers due to the blending of traits.

Detailed explanation-3: -When a tall and red-flowered plant is crossed with a dwarf and white-flowered plant, the phenotype in the progeny is dwarf and white.

Detailed explanation-4: -The example of codominance can be seen in plants with white color as recessive allele and red color as dominant allele produce flowers with pink and white color (spots) after cross-breeding.

Detailed explanation-5: -In codominance, both alleles are expressed together in the offspring. If we cross a red flower and white flower that have a codominance inheritance pattern, the offspring would be flowers with red and white patches on them.
