A true breeding tall plant is crossed with a true breeding dwarf plant. `F_1` progeny is 100% tall and `F_2` has tall: dwarf in the ratio 3:1
Name the patterns fo inheritance in which the ratio deviates from above. Also mention the deviated phenotypic ratio.

If a true breeding homozygous pea plant with green pod and axial flower as dominant characters is crossed with a recessive homozygous pea plant with yellow seeds and terminal flowers, then what would be the: genotypes of the two parents phenotypes and genotype of the F_1 offspring phenotypic distribution ratio in F_2 population?

In order to obtain the F_1 generation, Mendel pollianted a pure breeding tall plant with a pure breeding dwarf plant. But for getting the F_1 generation, he simply self pollinated the tall F_1 plants. Why?

If F_1 generation has all tall progenies and ratio of F_2 generation is 3:1 (Tall:Dwarf),then it proves:

List various conclusions drawn from a cross between red flowering plant and white flowering plant which give same genotypic and phenotypic ratios of 1:2:1 in F_2 generation.

In a plant tallness is dominat over dwarfness and red flower is dominant over white. Starting with the parents out a dihybrid cross. What is standard dihybrid ratio? Do you think the values would deviate if the two genes in question are interacting with each other?

Two Antirrhinum plants, one with red flowers and the other with white flowers were crossed. Show the possible genotypes and phenotypes of the progeny of F_1 and F_2 generations using the Punnette square. Explain the pattern of inheritance.
