When a tall and red flowered (both dominant) individual was crossed with a dwarf and white flowered individual, phenotype in the progeny was dwarf and white. What will be the genotype of tall and red flowered individual?

Q. In peas, tallness is dominant over dwarfness, and the red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated with 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 four offspring types.

Q. In a plant, gene ‘A’ is responsible for tallness and its recessive allele ‘a’ for dwarfness and gene ‘B’ is responsible for red coloured flower while its recessive allele ‘b’ for white coloured flower. A tall and red-flowered plant with genotype AaBb is crossed with dwarf and red flower with genotype aaBb. What percentage of their offspring would be dwarf white-flowered?

Q. Tallness (T-) is dominant over dwarfness (tt) while red flower colour (R-) is dominant over white colour (rr). A plant with genotype TtRr is crossed with plant of genotype ttrr. Percentage of progeny having tall plants with red flowers is

Q. A dihybrid tall plant bearing yellow flowers was crossed with a dwarf plant bearing white flowers. What is the percentage of progeny expected to be homozygous tall bearing yellow flowers?

Q. Tall red flowered Pea plant crossed to dwarf white flowered plant yields only tall red flowered plants. A test cross shall give a ratio of
