Detailed explanation-1: -The genotype for the pink flower is RW, and the genotype for the white flower is WW. This would lead to a 50% chance of the offspring having a phenotype of pink.

Detailed explanation-2: -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.

Detailed explanation-3: -The probability of producing a white flowered plant is 1/2.

Detailed explanation-4: -In Mirabilis jalapa when homozygous red flowered and white flowered plants are crossed, all F1 plants have pink coloured flowers.
