In peas, tallness is dominant over dwarfness, and red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated by a dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them Tall, Red = 138 Tall, White = 132 Dwarf, Red = 136 Dwarf, White = 128 Mention the genotypes of the two parents and of the types of four offspring

A garden pea plant produced axial white flowers. Another of the same species produced terminal violet flowers. Identify the dominant traits.

    In a cross between plants with purple flowers and plants with white flowers the offsprings of F_(1) generation all had white flowers. When the F_(1) generation was self-crossed, it was observed in the F_(2) generation that out of 100, 75 flowers were white. Make a cross and answer the following : (i) What are the genotypes of the F_(2) progeny? (ii) What is the ratio of 'White : Purple' flowers in the F_(2) generation?

    A pea plant with blue colour flower denoted by BB is cross-bred with a pea plant with white flower denoted by WW. (i) What is the expected colour of the flowers in their F_(1) progeny? (ii) What will be the percentage of plants bearing white flower in F_(2) generation, when the flowers of F_(1) plants were selfed? (iii) State the expected ratio of the genotype BB and BW in the F_(2) progeny.
