In peas, tallness is dominant over dwarfness and red colour of flowers is dominant over the white colour. When a tall platn bearing red flowers was pollinated with dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in number (a)Tall, red - 138 (b)Tall, white - 132 (c)Dwarf, red - 136 and (d)Dwarf, white - 128. Mention the genotypes of the two parents and of the four offspring types.
