In a case of red and white flowered Snapdragon, F_(1) plants will have flowers

If four o' clock plants, the gene for red flower colour (R) is incompletely dominant over the gene for white flower colour (r), hence the plants heterozygous for flower colour (Rr) have pink flower. What will be the ratio of offsprings in a cross between the red flowers and pink flowers ?

In Antirrhinium two plants with pink flowers were hybridized. The F_(1) plants producedred, pink and white flowers in the proportion of 1 red, 2 pink and1 white. What could be the genotype of the two plants used for hybridization. Red flower colour is determined by RR, and white rr genes

In a plant , tallness is dominant over dwarfness and red flowers are incompletely dominant over white flowers, the hybrid being pink. How many offsprings will be of tall height with pink flowers from a cross involved two plants each of which is hybrid tall and has pink flowers ?

Tall(T) is completely dominant over dwarf(t). Red flower colour ( R) is incompletely dominant over white ( r), the heterozygous being pink. Plant having genotype of TrRr is self pollinated. What would be the proportion of plants with dwarf and pink characters in the progeny

In a monohybrid cross of plants with red and white flowered plants. Mendel got only red flowered plants. On self-pollinating these F_(1) plants got both red and white flowered plants in 3:1 ratio. Explain the basis of using RR and rr symbols to represnt the genotype of plants of parental generation.
